* For new buttons spaces, automatically set horizontal/vertical align depending on size, instead of free. * Cleaned up the UI panel API. There's now a new uiBeginPanel function which takes a panel type, and a uiEndPanel which takes the final size. uiNewPanel* functions will be phased out. * Animate the re-alignment when a panel size changes, e.g. when enabling dupliframes. * Load ui scripts from the release/ folder first if it is available. This makes it easier to edit ui scripts, since it will directly use the original files which avoids having to run the build system. * Improve editing of panel types while blender is open. That means fixing some issues with lacking updates, overlaps, strange ordering. It even does an animation now when the panel resizes.
