Log:

Further work on the new image cache. This adds a patch from Greg Estabrooks to use in-memory cache of recently used images, which speeds up loading of recently used pages and more importantly scrolling through mythvideo or anywhere which uses lists containing images.

Images in the disk cache will now be reloaded if they have changed on disk since they were added.

The image cache isn't yet complete, in particular some memory savings can be achieved through keeping in-use images cached and excluding them from the cache expiry calculations.

This change touches more files than might at first seem necessary due to a switch from using QImage to MythImage where possible.
