$sanitize removes the tabindex property

[carpasse]

Hi guys

I am trying to sanitize some html with the $sanitize service of the ngSanitize module. Unfortuantely $sanitize removes the tabindex property so I can make the link "not fucusable".
so this piece of code:

$sanitize('<a ng-href="someUrl" tabindex="-1">go</a>')

will return

'<a href="someUrl">go</a>"

I have been searching a bit and I couldn´t find any security issue regarding the tabindex property so could it be possible to add this property to the list of valid attrs???

Seems like we need to add tabindex to uriAttr list here: https://github.com/chirag04/angular.js/blob/master/src/ngSanitize/sanitize.js#L207

@caitp If thats correct i am willing to send a PR.

Should probably go in validAttrs since it's useful for form controls too
