Also raise awareness of the hosted platform for osTicket

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

Fixes #667

And include the new location of the install SQL script

Drop old mcrypt class

Only use 8 bytes (64-bits) for the IV data (salt) for the encryption keys,
except for Mcrypt, which requires you to query the specific length and use
it specifically.

We should move initial data out of the install SQL file, which will make way
for a few things:

  * Internationalization -- which breaks the migrater model currently.
        Moving the data outside the install script makes it translatable
        without changing the SQL hash
  * Review -- Migrations which add more data don't highlight new features
        that need review to the adminsitrator

Support MariaDB version 10.0 and forward, which previously did not appear to
be 'greater than' version 4.4 as in php '10.0' < '4.4'. Performing a split
by the dots allows php to perform a numeric comparison.

This will facilitate a web-based export significantly easier

Allow the installation to use the same streams config and schema signatures
as the migrater

Allow the install to install mulitple database streams

Allow `streams.cfg` to be implied as 'core', which will default to only
upgrading the core osTicket stream.

Use signature to describe snapshots rather than md5

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.
