Floating Combat Text

[bboudaoud-nv]

We have discussed adding floating combat text to our application as another option for indicating hit/miss or damage to the target as many games do. This could be a good option, and comes with several parameters we probably need to add to config files.

We never implemented this but it should be comparable to adding a floating health bar as discussed in issue #23.

Added an initial attempt at this as of a recent commit. Floating text options for misses are currently not included and a single color is used for all combat text. I am going to close this issue for now, we can create more specific issues to deal w/ improving/fixing problems with the text.
