[RWP] changing tempo in reaper.

[Scott Chesworth]

As things stand currently, the beat/measure movement still applies
even when the timebase is set to time. You can use Ctrl+J to jump to
specific times by separating minutes and seconds with a colon, and you
can read the current position of the cursor in time using Alt+Shift+J.

Hopefully, an update will materialise sometime soon from Russia to tie
up the loose ends here, I'm hoping to be able to jump minutes instead
of measures and 5 second chunks instead of beats sometime.
