Multiple Sendmessage commands and 2.0b15

[malore]

After upgrading to 2.0b15 I noticed that several of my custom girder commands that sent multiple Sendmessages no longer work.

The Skip Fwd #2 (61) and Skip Bkwd #2 (62) commands, no longer seem to do anything and have been merged with Page Up(55) and Page Down(56). I was sending both commands (Page Down & Skip Fwd#2), so this was an easy fix.

I have several commands set up to give me custom skip lengths by sending the skip command multiple times. For example, I had a 30 min skip, by sending my 5 min ff_2 command 6 times. This worked great because the commands were sent so fast the video only updated after the last command was sent. Now it skips 5 minutes and then jumps back to were it started. I can get it working by adding a delay between each command, but now it takes longer and the video updates multiple times.
I suspect that changes made for mouse support might be to blame, but these changes might have been around longer and I just hadn't noticed.
