Departments without email will use the system default email as the default
outgoing email.

The setting is useful in making sure the staff members with access to the
department can get alerts and available as possible assignees.

Accept desired $format as part of class instantiation. System default is
used when none or an invalid format is provided

Add department setting to limit ticket assignment within department to
department members only. This is necessary for departments with strict
policy on who can access tickets.

The setting doesn't limit team assignment or auto-assignment via help topics
and ticket filters.

Previously, there was a bug in the ORM where magic properties would need to
be declared in the model class.

tnef: Fix major issue iterating over attar streams

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

The original logic would read the count of attributes in the stream and then
read the first attribute in the constructor of TnefAttributeStreamReader.
Then the iterator interface would call ::rewind() before iterating to the
first item. rewind() set the @pos attribute to zero, which would cause the
attribute count (4-byte int) to be interpreted incorrectly as part of the
first attribute.

The new logic sets the position at 4 after rewind()ing, and does not read
the first attribute twice. It also properly detects the end of the attribute
stream by the number of attributes advertised as the first four bytes of the
stream (read into the @count attribute initially).

On validation errors, `$faq` will be set to something non-null, like
`false`, but will not be an instance of a Faq article.

For PHP installations that have `mbstring.func_overload` enabled (set to a
value including `2`), the `strlen` function will be overloaded to use the
`mb_strlen` equivalent. Problematically, the internal encoding of `UTF-8`
will be applied to all file content, which will count UTF-8 characters
rather than bytes. This will cause the data to be saved correctly; however,
the `size` recorded in the %file table will be recorded incorrectly.

This patch allows the backend to report the size of the contents saved with
the request and provides a failsafe mechanism which will use the mbstring
equivalent if available, and the mbstring version is coded to use the `8bit`
as the encoding which will prevent reading characters.

This stems from a confusing similarity between the + operator for arrays
and array_merge() in php. Adding arrays will ignore items in the RHS where
keys are present in the LHS. Therefore, when adding numerically indexed
arrays together, only items on the RHS that have a key higher than the
greatest key on the LHS will be included.
