This commit enabled using keyboard keys to play the game.
However I did notice that if people smash the keys repeatedly when the game is not started or hitting the same key that has been pressed before can create many useless http requests on the slots which can cause a lot of load on the server.
I tried to disable/disconnect the signal and the slots but there was no method for it.
There should be a disconnect method for slots and/or disable method for events to prevent useless signals being emitted by http requests.

not by reference, so const qualifier of return type is useless.
Fix WtFindMysql.txt to support Fedora (mariadb / mysql)
add possibility to use external TinyMCE (e.g., CDN), add option tinyMCEURL

If configuration option tinyMCEURL is specified, options
tinyMCEBaseURL and tinyMCEVersion are ignored.

Probably, we need a possibility to specify custom URLs for
langs and plugins (TinyMCE 4 options external_plugins and language_url).
fix documentation of WTextEdit

\ref xxx "yyy
zzz"

So, anchor text should be written in a row.
