error could not authenticate twitter sharekit

For oath, you'lll need to use 'https://api.twitter.com/" as your request uri.  In Sharekit, the twitter addresses are hard coded.  You'll need to change "http://twitter.com" on lines 54-56 in SHKTwitter.m.

Also replace all "http://api.twitter.com" to use https in SHKTwitter.m
