Some basic re-branding before I start gutting things out...
Implement the file browser widget into the wave-editor-formerly-ab widget.
Internationalize that string...
Add a not-yet-functional sample graph...
Marginally improved sample graph drawing...
Improved drawing speed and CPU usage for sample graphs.
Oops...  Was accidentally setting the viewport update mode twice.
Greatly enhanced drawing performance, plus it looks much nicer now...
The super-epic-drawing-performance-enhancement of the year...

(Sample graphs draw sooooooooooooooooooo much faster now...)
sub-class the audio item viewer to have appropriate markers for each use-case.
Some fixes before I add the more important bits....
More fixing-up before the big stuff hits...
Not strictly related to the wave_editor branch, but because I'm
too lazy to switch branches right now:

Update the pt_PT translation provided by KVR forum users stormpack and
pc999...  Looks good, thanks guys :)
A few more wave editor UI tweaks as I work out the details of the back-end.
Basically working wave editor (playback only)

TODO:

Fades
Effects
Playback Cursor
As it turns out, fades were as simple as un-commenting code that I had
previously commented out...
More fixes...
Fix a truly horrid regression in the sample viewer...
Make it easier to change the size of the sample graph...
Warn about selinux barfing if trying to run the engine as root...
