make brasero retain extension when truncating file names for windows

Binary package hint: brasero

When I checked the "Increase compatibility with Windows" option before burning my disk, Brasero warned me that it would have to truncate file names longer than 64 characters in order to be Windows compatible. I allowed it and burned the disk.

The result was that Brasero did a hard cut of any characters after the 64 character limit. Of course, this eliminated the file extensions, which Windows needs in order to identify files.

Instead, Brasero should retain the extension (i.e., the last period, and any non-period characters thereafter) and cut more of the filename.

Examples:

ORIGINAL 1:
qwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiop.foo

BAD 1:
qwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiopqwer

GOOD 1:
qwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiop.foo

ORIGINAL 2:
qwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiop.asdf

BAD 2:
(Same as bad 1)

GOOD 2:
qwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuiopqwertyuio.asdf

Note that in the second example, the extension was 4 characters rather than 3, so more of the file name was cut.

Bonus points if you trim off extraneous whitespace at the end of a truncated filename, before reattaching the extension.
