Refactor Decode As dialog to use a model/delegate

The model provides a lot more flexibility and abstracting the
data from the view (dialog)

Noticeable changes from user perspective:
1. Value column doesn't always have a combobox.  If registered decode as
structure doesn't support multiple values, a simple edit box is used.
2. Existing value will always be a choice (default) in the Value combobox.
3. Duplicate values in Value combobox have been removed (for things like
UDP port where source port and dest. port are same)
4. When adding/copying a decode as item, only first column (table) is
editable, not the whole column.
5. Separator always present in Current protocol column to distinguish
"none" from rest of protocols.
6. "Current" protocol defaults to "default value" when first added to the
list instead of "none".

Noticeable changes from developer perspective:
1. Code is much more spread out, but most new additions (like DCE/RPC support)
should be limited to the model class (maybe delegate).  The dialog class
probably won't change much anymore.
2. decode_as_dialog.ui is much less useful because information is provided through
model and delegate.
