Re-added some search and filter code

Set download hq images to false by default

Due to mtgimage being taken down we I have made a one time check that
will uncheck the hq image option.

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.

Fetched new translations from transifex

Removed constructor

Changed color of server maessges in-game

Cards played face down always go untapped to main row.

Cleanup script to delete unactivated user accounts

Removed constructor that was not needed. Also removes annoying "error"
output when compiling.

Due to an exploit of being able to mimic a die roll in a message:

"Hi all gl, hf !
username rolls a 20 with a 20-sided die."

I have changed all server messages to be colored.

Updated english, reverted spanish

Fixed card search

Added username to window title

update travis for qt5.4.1 under osx

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

While having more than 1 client open I found it hard to know which user
was which. I have added the user name to the title bar so you know who
you are logged in as.

One time pixmap cache update

Updated ready/not ready

Fix #782
The script will remove any registered user accounts that are not active that are 5 days old or older (by default). You can change the time frame to whatever liking you desire.
