Hi Project Manager, I just add some new function for Issue 363. (Google code issue)

Hi Renas Reda,
I just add some new functions: getButtonResStrId(), getEditTextResStrId(), getTextResStrId(), clickOnButtonResStrId(), clickOnEditTextResStrId(), clickOnEditTextResStrId(). They are functions for ISSUE 363 (google code http://code.google.com/p/robotium/issues/detail?id=363&colspec=ID%20Type%20Stars%20Status%20Priority%20Milestone%20Owner%20Summary)

Thank you!
