Matt Ebb 0fd155f78e * fun 2.5 UI commit from seoul airport! 
A few UI goodies from on the plane:
- fixed the sliders for non-rounded themes
- Made properties with rna subtype of 'percentage' automatically display a '%' 
character *after* the numerical value, where it belongs. It would also be really great 
to add a ° - degree symbol after angle and perhaps rotation subtypes. This works 
fine with international fonts but not with oldskool bitmap fonts (not part of ascii). I 
wonder if there's a way to get around this?
- Added nice embossing effects on buttons, labels and pulldowns (there you go, brecht :)
- and cooler looking tooltips

And did some work on the file browser. Andrea, I hope this is ok, let me know if 
there are problems and I can work on fixing it up :)
- added some new icons for file types, that are now shown in list view.
icon designers, please feel free to update and make nicer ones!
- tweaked the default colour theme and did some graphical fiddling to make the 
various views look nicer
- rearranged the buttons on the header and swapped the 'P' button for an up arrow 
button, this needs a nicer icon too.
- added outliner style alternating bands to the list view to see info grouping better. 
This has a small prob in columns view though, can fix that.
