And freshen up the upgrading guide

Also, run the tests in the packager. The packager will automatically run the
regression test suite prior to packaging a release. The package will not
build if there is at least one fail from the regression tests.

Useful for initial installs, where deployment of the `setup/` folder is
required for the initial install. Thereafter, deployment can be run without
the setup option so that the rest of the codebase can be maintained (already
supported)

 * web.config
 * pages/{.htaccess,index.php}

Fixes #667

And include the new location of the install SQL script

This will facilitate a web-based export significantly easier

This will allow an administrator to visualize the files changed in the
deployment before actually copying out the new files

Turns out that the $args passed into the run() method of the Unpacker are
not correctly utilized and so, it is not correctly extensible

This will allow folks following the git development model to checkout the
sourcecode to one folder, follow an upstream git brach, and deploy the
osticket installation from a current branch to a location somewhere.

The deploy process differs from the unpack process in that it does not
assume to be inside an 'upload/' folder from the install zipball, and it
does not deploy the 'setup/' folder.

The include folder is still supported to be installed elsewhere.

- Force destination folder to always have a trailing slash
- Log if verbosity is set to stdout
- Use MD5 to see if copy is necessary

Inside cli modules, use internal stdout and stderr objects rather than
writing directly to the PHP outputs. This will allow for significantly
easier regression testing integration.

Include all the modules for `php manage.php --help` invocation. Also, pass
the parsed arguments and options to the Module::run() implementation.

Aggressively package ALL files in include directory - excluding live config file or swap files.

Exclude ost-config.php
Use the correct package name

Use minimized version of css.

Implement remote cron as api task (more to come)
