TBImageManager improvements #118

TBImageManager needs these improvements to be useful:

Cache with configurable size. Currently it throws away images immediately when they are not in use.
HasImage(name), NewImage(name) in addition to the current GetImage(name). GetImage could still load (treating name as filename) synchronously for backward compability.
Possibility to change image content (and probably state for EMPTY/LOADING/READY). Needs listener callbacks.

The last two points must make it possible to off-load loading to worked thread.
