The global shortcuts were removed in favor of key events
which are only triggered when a widget has focus. This is
necessary to allow different widgets to react differently
to the 'enter' key. The current key configuration is:
search edit focused:
  * left/right: decrease/increase card count for selected database card
  * enter: add selected card to deck
  * ctrl-enter: add selected card to deck sideboard
  * ctrl-left/right: decrease/increase card count in sideboard for selected card

database focused: the same as with search edit.

deckview focused:
  * left/right: decrease/increase card count for selected deckview card
  * enter: increase count for selected deckview card
  * delete/backspace: delete selected card from deck

reverted cardinfowidget to its original form at commit
95c6058d before i messed with
it. i didnt intend to make changes to it.

cardframe is now a stacked widget that prefers to show the card picture
only so that the screen can be more space efficient and the card pixel
map can be displayed as a larger size. however if the card pixel map
can not be loaded for some reason, the cardframe class will automatically
switch to the text version of the card.

a menu item was added under the database menu to allow for users to
prefer card text only.

clear the text box when the '+' button is pressed or
when the filter attribute is changed.

also changed the frame style to match the card frame style.

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.

also refactored much of the filter list code to be much
cleaner and modular.

enable/disable check boxes still not functional

filter builder takes filter options from user, then adds
completed filters to the filter tree. the filter tree does
not currently do anything. in the future it will filter the
cards in the database view.

When something happens, the taskbar icon lights up/the dock icon
bounces. This can be annoying, so here is a setting to disable that.

"The price tag feature currently has two bugs.
1. The final price that a card ends up with is the one in the last set
alphabetically, instead of the one from the set with the lowest price.
2. Black Lotus Project sometimes gets in prices for cards from Masters
Edition, for some reason. This set only exists in Magic the Gathering:
Online, i.e., not physically, and should not be considered. This might
be considered a BLP bug and not a Cockatrice bug.

This patch fixes those two bugs. I also changed the price value to be
based on BLP's "price" value instead of the "average" value. Seems more
logical."

QPainter.drawRect()

Previously this behavior only occured for instants and sorceries

Woops, missed a file

Missed some parentheses

Click-holding on a card then immediately releasing now properly changes the
cursor from a closed hand back to an open hand
