When searching for a card the line edit will not be empty, so this check
is not needed. The performance when the line edit IS empty will take a
slight hit, but you really want additional performance when searching,
not when the line edit is empty.

Removing will increase performance.

Previously would try to match the card name, if nothing is found, then
we would try again with the simple name.

I have now made it only the simple name version. We do not need to
perform the first check. Should help a little with performance.

Tokens from decks will now show in the token dlg window

It is awkward to have to use precise punctuation when searching for
cards. Planeswalkers and legendary creatures often have "," in the name
and you have to enter it.

This commit means you no longer need to do that.

+ Can use " " in place of "-" (example: Wilt-Leaf Liege)
+ Can use "" in place of non word chars (Example: Hero's Downfall and
Ajani, Caller of the Pride)

I had previously removed some filtering code that would allow users to
filter cards using our filtering tools. This functionality has now been
re-added.

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)
