Use twitter RESFful API instead of twitter search for getTweetsFrom

This is a big help @jherencia. Thanks so much!

A key reason to use the REST API is the following limitation in the Search API:

The Search API is not complete index of all Tweets, but instead an index of recent Tweets. At the moment that index includes between 6-9 days of Tweets.

We've just ran into this.

Updated patch, mostly for some tweaks:

• The cache_get() statement was inadvertently removed, so it kept loading the data each page load.
• Several small fixes for coding standards.
• I added some more comments.

FYI another change I made was to move loading the CSS file to the info file instead of hook_init().

Updated again to better identify errors from twitter (instead of just saying "oops"), and also separate out the magic code that does the work so it can be more readily reused elsewhere, e.g. by a CTools plugin.

Patch in #8 works for me

I committed this with some changes. Thanks!

Is there a new dev under way?

I am helping zendoodles get twitter_block ready for a 1.0 release, and she's helping me with BlogAPI :)

Closing because I'm impatient and don't want to wait for the bot to clear out the queue.

Minor changes.
