Merge branch 'release/v1.7-RC4' into develop
Bump version number post RC4 release
Add package script and scripts/ folder for scripts
Add management meta script

Which will allow for a modular approach to command-line scripting of the
osTicket system. Hopefully, it will alleviate the need to copy+paste code
between scripts and otherwise duplicate functionality between locations. It
will also allow for easier administration of osTicket by shipping scripts to
do things like database maintenance, statistics exports (collectd), data
exports, etc.

The first example script include the capability to unpack the osTicket
installation/upgrade tarball to the destination install path with optionally
placing the include folder in a different location. The script will monkey
patch main.inc.php so that the INCLUDE_DIR define will point to the
installed location of the include/ folder.
