replaces the non-repository managed web interface for pihole and keep…

[ghost]

This PR will replace the non-managed /var/www/html/admin directory with the git managed repo.

The first time the script is ran on an existing installation, it will:

• Remove the existing /var/www/html/admin directory
• Clone jacobsalema/AdminLTE to /var/www/html/admin

Subsequent runs of this script will:

• Pull the latest master branch from jaconsalema/AdminLTE to /var/www/html/admin

I'm not sure if this fits in the scope of what you hope to do with pi-hole, but if it does I would like to call this script in the basic-install.sh process. There would need to be some minor tweaks, but I think it would make updating the web interface a trivial process.

Below is the process debug:

First Time Run:

# bash update-webinterface.sh 
+ WEB_INTERFACE_GIT_URL=https://github.com/jacobsalmela/AdminLTE.git
+ WEB_INTERFACE_DIR=/var/www/html/admin
+ main
+ prerequisites
+ [[ 0 -ne 0 ]]
+ '[' '!' -d /var/www/html/admin ']'
+ type git
+ is_repo
+ '[' '!' -d /var/www/html/admin/.git ']'
+ return 1
+ make_repo
+ rm -rf /var/www/html/admin
+ git clone https://github.com/jacobsalmela/AdminLTE.git /var/www/html/admin

This would act as a nice mechanism to keep it up-to-date. I'll test it out and see how it works.

This works great. One minor thing is that when my interface was updated, the last line still said Already up-to-date., implying nothing updated, which it did.

Running it a second time just returned this result:

Already up-to-date.

So maybe the verbiage could be changed, but besides that this is great!
