Also, the final version of the system will not require the `gettext`
extension for PHP

Also add several lint fixes for packaging

Also, write js and css links to be forcibly reloaded by the browser after
deployment

Instead of allowing the backend to send a redirect URL, which doesn't make
sense on the command line

Add CLI import/export support for organizations

Output headers on export

Implement CLI user import/export in a well formatted CSV file. Name and
email address are the only supported fields at the moment.

Add the current backend to the list results output
Add a --limit switch to support limit results sent to a command like
`migrate`

Allows for backend listing, file listing, single file dump and file
migration.

Allow arguments to have sub-command 'options', so an argument like 'action'
can have a specified list of values, each with respective help output.

And install initial data in target language. Also configure help tip
popovers to be in the configured, default system language.

Also, if any non-shipped .htaccess files exist, don't clean those either

Fixes #60

Allows the deploy script to remove files in the target that are not preset
in the current repository. This patch assumes pure stock osTicket
deployments -or- that the files deployed in the target are also present in
the local repository.

When the include path is written in bootstrap.php, ensure that extra slashes
are not accidentally added

Use a PHP setup which uses the built-in PHP tokenizer to parse and traverse
PHP scripts to determine (possible) access to uninitialized variables

Fixes #20
