Added YouTube / GitHub / Steam to user profile

[kung foo man]

Hey all,

you can now add your YouTube / GitHub / Steam profile links to your user account. I had to add some regexes to prevent the input against XSS attacks, so this is what I came up with:

^(http|https)://(www.)?(youtube.com|youtu.be)/((c|channel|user)/)?(\+?)[a-zA-Z0-9_\-]+(/)?

http://youtube.com/YourGooglePlusName
http://youtube.com/+YourGooglePlusName
http://youtu.be/+YourGooglePlusName

^(http|https)://(www.)?steamcommunity.com/(id|profiles)/[a-zA-Z0-9_\-]+(/)?

https://steamcommunity.com/id/kungfoo_man123/
http://steamcommunity.com/id/kungfoo_man123/
https://www.steamcommunity.com/id/kungfoo_man123
http://www.steamcommunity.com/id/kungfoo_man123/
http://steamcommunity.com/profiles/NUMBERS_GO_HERE

^(http|https)://(www.)?github.com/[a-zA-Z0-9_\-]+(/)?

https://github.com/kungfooman/
http://www.github.com/kungfooman-asd

Great site for testing: http://www.phpliveregex.com/

If any valid link might not work, please tell me.

Are the any other sites which you wanna add to your profile?

Random ideas welcome aswell.

Edit #1: Added youtu.be, G+, and Steam /profiles/
