Display number of alive aphid, ladybug & ant in game next to time & score.

A smart way to do it is to have the 3 icon as text char & to personalize the function that return glif. (As Unciv project do)

[x] Be able to create 4 50*50 icon to the game. 1 for each creature. Create them from big creature with a black outline.
[x] Have a personalized getGlif function to represent text in GUI that can return glid from true font or icon if it match the uft8 char for icon.
[x] Use personalized getGlif to display the number of alive creatures ingame.
[x] Use personalized getGlif to display icon instead of creature name in level description.
[x] Use it for display Creature that will be into the level in menu
[x] Fix color text
