P/T column is really narrow. It should go before Card Type, so Card Type can expand into the remaining space.

Improves #1671, assuming I got this correct.

Untested!

Card search will now order the following way:

1. Exact match at top
2. Exact match with preceding values sorted lexically.
3. Match contained in word sorted lexically

the original layout is actually more space efficient if using CardFrame
instead of CardInfoWidget and reducing the size of the deck editor
toolbar.

this commit also removes the old search feature by removing the search
button and the clear search button. the clear search menu item is left
in place, however it now clears the filtertree.

finally, the stretch factor for the right frame in the main layout was
reduced to zero so that the card database gets priority for extra space.
this makes more sense because the deck editor does not actually need
very much horizontal space.

renamed filter list modules to filter tree to more accurately reflect
the nature of the data structure.

enable/disable check boxes still not functional

improved token dialog w/ storage inside the deck list - now we need a reliable online source for token data (preferably with pictures)
