Increase twitter frequency options (add 1 & 2 minutes options)

I believe that now that twitter increased the limit on their API ST! should add more options in the "Frequency" setting of twitter. The lowest value now is "every 5 minute" that it is high for those that follow twitter exclusively from ST!. As other options will still be available anyone can decide how often they want to check twitter through socialthing (if they use other clients also).
I believe we should have "every 2 minutes" and "every 1 minute" options.
