More useful values for CTDA\Type

[SeeSharpCode]

Enhancement - need to display more useful values for the CTDA Type field, like what xEdit does. There's a few ways this can be implemented:

1. Make a new function which yields the display value for certain fields
2. Determine values on the frontend (within zEdit)
3. Change the xEdit library in xEditLib to yield the string value using serialization/deserialization.

I think would prefer the last option because it doesn't involve an increase in complexity (as in options 1 and 2) and builds the enhancement into the xelib API so other applications can leverage the "nice" values in the future as well.
