Little fixes in setup.txt, tx-tc-ftr-500.js and tx-tc-500.js:
1. Smilies with a trailing "[" can cause problems with subsequent BB-Codes, thus eliminated "frown = :[" from setup.txt
2. When entering a comment with several lines, select several lines, then press <Delete>: No resize happened
3. Entering comment title and giving <Enter> submitted the form to page
4. After edit and save comment, the save comment button was not enabled anymore.
