Proper capitalization in the project name.

If #1813316: Merge with subpathauto? happens, then this won't matter, but till then...

According to these:

Writing .info files (Drupal 7.x)
#1346158: Decide on coding standard for capitalization of module names [policy, no patch]

Proper Case should be used. So, "Extended Path Aliases " instead of "Extended path aliases ".
