This patch adds support for automatic date and time formatting based on a
selection of locale. The locale can default to the system or user specified
language+locale, or can be elected separately. For instance, English
speakers can pick between US, GB, and many other English speaking locales.

This also removes the need of the %timezone table and uses the timezonedb
built into PHP 5.3+. User's can now select from a much longer list of
database and no longer need to deal with the DST checkbox.

*This is a major redesign / rework of the osTicket base*

This patch drops the concept of static ticket metadata and allows for an
admin-configurable arbitrary data that is attachable to tickets

The system is architected such that the base osTicket install now comes with
a "default" form that has fields for subject, name, email, and phone number.
This form is editable to allow for the addition of arbitrary other fields;
however, the basic fields must remain in order to be associated with a
help-topic and attached to a ticket.

This concept can be expanded to allow for arbitrary data associated with
registered clients or ticket thread items.

Forms are comprised of sections. Sections have a title and instructions
properties and a list of fields. Fields have various implementations to
represent different data such as text, long answer, phone number, datetime,
yes/no, and selections, and are configurable to define the look and feel and
interpretation of the respective form field.

Dropdown lists are represented as "Dynamic Lists", which are
admin-configurable lists of items. Dropdowns can be optionally represented
as Bootstrap typeahead fields.

This also adds the start of a simple ORM which will hopefully be expanded in
the future to support multiple database platforms. Currently, only MySQL is
implemented.

If the GD extension is not available for the PHP installation, then use a
copy of the default client-site logo with the alpha channel removed.

Assume that text in the database is encoded in UTF-8 and assume that it is
HTML text and the entities should be decoded prior to display in the PDF.

Fixes #756

Also converts ROOT_DIR detection to always use forward slashes. And it fixes
the removal of the leading double-backslash on Windows UNC names (fixes #649)

Add SLA to ticket info table.
Move subject to the top of ticket thread.

Change the with of the info table

Add print options supports - staff can now print a ticket thread without internal notes + select paper size on the fly

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.
