Log Message:
-----------
BGE: Font Object support to animated (object) colors
implemented the support for animated colors and a workaround for non animated colors. To be cleaned if/when this bug is fixed:
[#25487] BGE: Object Color only works when it has a keyed frame

* also increased the size of the text. Now it supports 280 (or 140 unicode) chars.
