Especially on Galera clusters, search indexing with MyISAM tables will cause
unstable clusters and loss of data. For standalone clusters using MySQL 5.6
or MariaDB 10.0, the database default table storage engine can be used,
since either support fulltext indexing.

Determine and set a reasonable max file size on install
Remove file extension restrictions - transition to mime types

For fields with `name`s which are the same as other fields on the new ticket
form (such as `time` used with the new ticket by staff form), ensure that
data from the fields outside the main ticket form ("Ticket Details") is not
mingled with fields inside the form.

Since this is only a problem for web requests, and specifically new ticket
by staff requests, this patch only applies the field name to data matching
for non-web requests.

Add order by method to ticket status list to return appropriate sort columns
Delegate __get method in CustomListHandler to the parent list

Compare the database `state` field rather than the admin editable status
name.

The real bug was setting the source of the ticket form — not the fallback to
the form entry source.  Falling back breaks edits.

Also fix a crash when re-rendering the new ticket by staff page after a
validation error.

Use the cdata field when searching and sorting the ticket listing on the
client side.

This patch fixes a small glitch where validation might be bypassed for
fields for agents. Previously there was a glitch where required fields would
have their validation errors ignored.

Since users can already log in via their email address, offer a friendly
error message when agents configure the user name to be an email address.

Footer should not be in #pjax_container, because the footer is not rendered
for non PJAX requests.

When processing the value of a DynamicFormEntryAnswer, if there is no
database-backed, value, then use the value of the associated field.

This patch also makes a slight edit to mPDF to allow better detection of
substitions in characters, as the DejaVu fonts shipped do not support Thai
glyphs.

This allows administrators to select a default value for selection fields
deriving from Custom Lists. This has been implemented on the ChoiceField,
but was forgotten on the SelectionField

This addresses cases where incoming emails doesn't include charset and
mailbox may include non-ascii characters.
