If the sounds path is unset in the settings and a “sounds” directory
doesn’t exists in the user’s data directory, install the sounds files
and set the settings value accordingly

 If none of the gameboard images is set and and the user’s data
directory doesn’t contain a “zonebg” directory, create the directory,
copy contents from cockatrice’s app bundle and sets the config
accordingly.

Better error message and allow the user to still connect

Ref: #102

Add HQ card option

* add multiverse id to cards.xml
* remove pictures urls from cards.xml
TBD:
* fix/clean oracle’s gui
* add support in cockatrice

removed LEFT/RIGHT increment/decrement while
the card database/quicksearch edit have focus.
LEFT/RIGHT increment/decrement remains while the
deck view has focus.

also, now the card database delegates focus the
quicksearch editor so that any characters typed
while the card database has focus will narrow
the search down using the quicksearch filter.

`control`+`alt`+`-`/`=` now increment/decrement
the mainboard and `control`+`alt`+`[`/`]` now
increment/decrement the sideboard (alt could not
be used alone as OSX inserts special characters
using alt.

in the case of AND'ed filter terms, returning true
from acceptCardAttr will be equivalent to ignoring the
disabled term, but in the case of OR'ed terms,
returning true will incorrectly cause all cards
to be accepted.

the fix is to test for whether the term is enabled
before calling acceptCardAttr and continue if
disabled.

this should fix the compilation issue mentioned by mattkelly
