Subject: Added a flickering cursor for input menu fields. The code is kinda of sucky, so feel... 
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=fa7769802333d53d9ec439e675da508a59b54bdf;p=supertux.git

Added a flickering cursor for input menu fields. The code is kinda of sucky, so feel free to clean it up.

Unfortanely, there isn't any '_' charcter, so I have to use '-' :(
I hope, we will soon add a new row of characters.
