twitter_block 7.x-1.0-beta1

A more stable release than the first alpha. Still needs work, but the primary functionality is here. I will not be rolling an rc until the admin pages are finished, documentation written, and simpletests are implemented.

For this release I've added the twitter user and avatar to the tweets, and tweaked the css a bit. Tthe output is still fully theme-able by overriding theme_twitter_block_tweets() and/or theme_twitter_block(). Also notable is the linkification from benjamin.wallberg and several bugfixes:

#1090202 Twitter_block_admin_form not blocks
#1043846 Remove access twitter block perm.
#1052570 Tweets are now filtered as expected.
#1049180 Add language selection to search builder. Includes additional validation too.
#1111738 Linkify tweets. Well done @benjamin.wallberg
#1096134 Gracefully handle Twitter API limit of 150 calls per client. Another great contribution from @benjamin.wallberg.
