GUI: Add partial support for portability severity.

Add 'backend' support for the new 'portability' severity. The new
severity is handled, converted to new SHOW_PORTABILITY and added
with correct type to the result view.

There is no menuitem/toolbar button to show/hide portability
items. Likewise there is no line for portability issues in stats-
dialog.

Ticket #2106 (More severities and new xml format)
