If there is a match in Whitelist/Blacklist/Wildcards, `[ ! -t 1 ]` will cause the search to end if the terminal is closed when the script is called. This has the intended effect of allowing a user to search for a W/B/W domain (as well as all the adlists it's found in) using `pihole -q` via Terminal, but the script will stop searching after a W/B/W match when called by the block page.
While testing to make sure `pihole -v` would output `pihole-FTL version`, I noticed some options didn't work how I expected them to. For example, if I use `pihole -v -p`, I would expect to see the version output of Pi-hole Core. Instead, I'm informed that it's an invalid option.
I've had the following things in mind while rewriting this:
* I'm operating under the assumption that FTL is only installed if the Admin Console is (Line 113 exit 0)
* I have modified the help text to only output with `pihole -v --help`
* I have modified all output to be more similar to the output style of `grep` and `curl` (Ditching ":::")
Testing output:
```
w3k@MCT:~$ pihole -v
Pi-hole version is v3.0.1-14-ga928cd3 (Latest: v3.0.1)
Admin Console version is v3.0-9-g3760482 (Latest: v3.0.1)
FTL version is v2.6.2 (Latest: v2.6.2)
w3k@MCT:~$ pihole -v -c
Current Pi-hole version is v3.0.1-14-ga928cd3

w3k@MCT:~$ pihole -v -p --hash

```
* Disable `include-conf-enabled.pl`, as blindly enabling HTTPS (as Let's Encrypt does by having a file in that folder) creates Block Page inefficiencies
* Make Block page handle JS request rewrite, allowing users to better utilise their `lighttpd` service
* Make Block page handle debugging Pi-hole header
* Make Block page redirect users from `pi.hole` to `http://pi.hole/admin`
* Allow scanList() to search files using a wildcard by removing quotes wrapped around `${list}`
* scanList() will not provide a domain ouput on each string if exact is specified (`grep -l`)
* Remove unused processWildcards() function
* Return a message if no domain is specified
* IDN domains are converted to punycode when running a `pihole -q` search if the `python` package is available, otherwise will revert to current behaviour
* Scan Blacklist & Wildcards first, exiting from search if a match is found (Fixes#1330)
* Use one `grep` subshell to search for all "*.domains" lists at once (opposed to looping to get every matching file name, and then spawning a `grep` instance for every matching file)
* queryFunc() will not return "(0 results)" output from files where no match is found
* Sort results based off list number
* Return a message if no results are found
* An "About Pi-hole" link on the block page provides an ELI5 explanation to those not familiar with Pi-hole
* An email contact link on the block page provides users of your Pi-hole with a means to easily get in touch with you
* Browsing to your Pi-hole's address will show a simple "landing page", which can be replaced by adding "landing.php" within "/var/www/html"
* Users manually browsing to file/image based content (i.e: non HTML based content) on blocked sites will be greeted with a small "Blocked by Pi-hole" image
* Sites that are manually blacklisted will display a notice of this on the block page
* Sites that aren't directly blocked, but have a CNAME record, will show a notification on the block page (e.g: If raw.githubusercontent.com is not blocked, but github.map.fastly.net is)
* On the block page, "Back to Safety" now directs the user to "about:home" if Javascript is disabled
* Whitelisting is disabled for installs without a password, or if a client does not have Javascript
* Known issues:
* Admin Console needs a text field under "Web User Interface" where the admin can enter a preferred contact email when a site needs to be whitelisted, to be saved to setupVars.conf with the key "ADMIN_EMAIL"
* Admin Console needs a text field under "Networking" where the admin can enter their Pi-hole's externally contactable FQDN, allowing access to their landing page when browsing to mypi.duckdns.org, to be saved to setupVars.conf with the key "FQDN"
* I am not aware of expected output of `$_SERVER["VIRTUAL_HOST"]`, so I have assumed it should be filtered as if it's a domain
