Spelling and readability fixes for /include/class.* files
  - Fixed some spelling mistakes
A couple more spelling/readability fixes.
  - More fixes

1) Ability to limit who can post a reply
2) Expanded staff's stats view.

Example use case %staff.name  %team.name ... etc.

* Auto rehash MD5 based passwords

- Move access to it's own table.
- Refactor what department membership means in relation to group access

Add ticket class  (just incase the parent doesn't have it included)- required to fetch staff's ticket stats.

Remove LEFT JOIN to time zone table in order to support upgrading from 1.6* to 1.7 + Fix bug on getDepts

Allow staff members the ability to select a default paper size which will be
used in printing tickets via PDF. In the future, this may be overridden per
ticket by a dialog box at print time.

And correct several undefined function errors from several source files. So
while function names in PHP are considered case-insensitive, it still makes
sense to use consistent camel casing for both defining and calling methods.
The lint test searches the code base for method calls, and then searches the
code base again looking for a function definition matching the name of the
function invoked. It's not failsafe, because it doesn't detect the class
from which the method should belong, so it's likely to have false negatives.
Furthermore, it won't work well for PHP 5 where several classes are built
into PHP (and aren't searchable in the osTicket code base).

Remove the include/staff/api.inc.php as it no longer appears to be used (and
contains references to undefined methods).
