This fixes a regression in the option parsing where --setup would be
interpreted as --setup -e -t -u -p

Also, some parts of osTicket, like internationalization and plugins need
read access to a directory in order to get a list of installed plugins and
language packs.

(rather than deleted after install)

This allows the MANIFEST to be hidden from HTTP requests since the entire
include/ folder is already denied for Apache.

As an option, this will allow preventing deployment of files not tracked
with git. It's also about twice as fast as the PHP version.

This allows files which are edited on the fly during deployment to be
tracked so that they are not unnecessarily deployed again in the next
deployment run. It also allows for more creative deployment strategies using
something like `git ls-files -s`

This is required with the connection to Dept::getEmail()->send(...)

This patch (which needs further development), introduces an extra field to
the %attachment table to store a file's name, in the event that two files
with the same content are stored in the database with differing names. In
such a case, the name is stored in the %attachment table. This allows the
attachment to specify a different name each time the same file is attached
to something in the system.

Also make forms deleteble by marking them as deleted and hiding them from
the form listing. This ensures that custom data always has a link back to
the form.

This allows detection of some incorrectly-typed email addresses before
tickets, users, and agents are created.
