- Allows the string "false" to be used in the XML payload as the documentation demonstrates, and have that be interpreted as a boolean false.
- Switching $alert/$autorespond to use isset(), and forcing those variables to be type-casted to booleans.

It was previously not possible to use the `alert` and `autorespond` flags in a negative way to prevent those two events, since the ternary operator would have used the `false` ternary value, which was `true`.  This corrects that by allowing the default of `true` to be used only when the `$data` array does not have the appropriate keys set.  Assigning `$data['source']` was altered to use the same formatting and caution against an undefined index error.

Fix subject display when a ChoiceField is used

There was a slight issue when transitioning from a short answer field to a
drop-down field, and when the CDATA table is dropped and rebuilt.

Rollback to auto commit, except for sequence  iteration

Reviewed-By: Peter Rotich <peter@osticket.com>

Prior to osTicket v1.9.4, drop down lists only allowed for a single entry.
After upgrading to 1.9.4 the database data for drop downs changed to allow
for multiple entries. However, the old data format was not properly handled
by the SelectionField::to_php() method which handled interpreting and
upgrading the database data.

Keeping the transaction active for the entire request increases the
likelihood of a deadlock on Galera clusters.

InnoDB tables for search indexing where possible

Reviewed-By: Peter Rotich <peter@osticket.com>

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.

forms: Fix validation errors for field `name` matches

Reviewed-By: Peter Rotich <peter@osticket.com>

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.
