Private Chat Tab Update

Cleanup git links

Additionally, use the same name for “private chat“ in all menus (we had
“personal talk” and “direct chat“ before)

fix #811

Kick message no longer takes you to kicked tab

Fix for filter

updated contributing.md

fix for #749
+ You can now search for sets using lower case: "frf", "dtk", "rtr" and
so on.
+ You now need exact matches on set short and full names. "rtr" and
"return to ravnica" will work. "return" will not work.

Added optional card scaling setting

- fixed typos
- included labeled links

Resized game view columns

+ Users can now enable/disable the mouse over card scaling.

Script to add the first admin account

Updated user games window size

Added shortcut to clear chat

Previously all columns were the same width, making it cramped. I have
resized them to give a better initial width.

F12 will now clear the chat in the main chat.

fetched updated translations from transifex

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.

Script to add the first admin account to the servatrice database.  Running this script after setting up a servatrice server will add the user account "servatrice" with the password of "password".

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.
