Summary: Limit number of FBOs in use at a time

Initial Comment:
With OpenGL, each time al_set_target_bitmap() is called on a video bitmap we automatically create an FBO for drawing into it. However it seems some OpenGL drivers have a limit on the number of FBOs allowed at a time. This means when you load 1000ds of textures at the start and all al_set_target_bitmap() on each to for example do some small conversion, it will inexplicably fail with such drivers. For now http://docs.liballeg.org/opengl.html#al_remove_opengl_fbo can be used to fix this (like in my personal code), but a better solution might be to simply limit the number of FBOs to a sane value, maybe 50, and after that start re-using them.
