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.

Fix crash submitting new ticket with validation errors

And fix an error message typo

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.
