Updated to Bootstrap 3.0.2 released Glyphicons fonts

The fonts from the Bootstrap 3.0.2 release implement "Update Glyphicons font to resolve #10106", see https://github.com/twbs/bootstrap/commit/dca7be6b67df60a094c1e292871ee5be4c1edd8d and further references for details.

I actually know nothing about this topic, but looking around in the gae-init source tree spotted that their last update seemed to be a bit out of whack with the Bootstrap 3.0.2. Then this monkey did a quick branch, downloading the official release, and copyied over some files; and yes there was a diff; quick look at Bootstrap project and history and presto, it looks like there is a reason to update.

This also updates file permissions, which is in-line with the Bootstrap project; see "Remove execute permissions on fonts files" on the history of the folder at https://github.com/twbs/bootstrap/commits/master/fonts
