* Added back vertical scale markings for vertical scrollbars. Currently untested (until IPO Editor can be put back in). Also, there was a special exception for the Sequencer, which will need to be checked when the time comes too.
* Fixed the display of frame numbers in scrollbars. Was caused by error in using an int, where a float was required (this is one place MSVC gives better warnings than GCC).
* Outliner horizontal scrollbar now displays a more useful range. The previous range was based on screen width, not width of content.
* Outliner horizontal scrollbar now draws with bevel-highlight line again. Was missed out in a previous commit.
* Added simple toggle Frames/Seconds operator to TimeLine to test if the View2D code is working right for this. This uses the same hotkey (TKEY) as it's counterpart (with a menu for input) did in previous incarnations of Blender.
