Remove executable bit from images

[balasankarc]

While packaging this gem for Debian, these executable bits on images caused errors. Also, images being executables doesn't seem right.

Nice one @balasankarc, could you please remove the executable bit from all files that has it to merge the pull request (I believe there are 388).

[balasankarc]

@jonathanwiesel All files? Or all image files?

[jonathanwiesel]

@balasankarc all image files, sorry

[balasankarc]

@jonathanwiesel Is there any remaining? ls -l on assets/images give me none.

[jonathanwiesel]

@balasankarc I used the following command surfing around and found 388 files with the "x" flag in the assets/images directory. Your commit seems to refers 300:

$ find . -maxdepth 1 -perm -111 -type f

[balasankarc]

Ok, I also saw that. But, when I tried it on my repo's HEAD (after applying this MR), I got 0. :)

@balasankarc you're right, the "300" is a diff limit in the Github interface; however in the shell the diff show 388 changes and no "x" flags.

Thanks
