[OpenSER-Docs] First Clean-up Patch for Documentation

Hi, Guys... I finish the first clean-up of the documentation. It consisted by: 1) remove all FAQ and DEVEL files considered empty in content (no content at all or just the default lines); 2) remove of the <RevHistory>/</RevHistory> tag (and of course anything Between them); 3) remove the comments at the EOF that beginned with "<!-- Keep this element at the end of the file"; The attached file (in ZIP format) is the resulting SVN DIFF file. It was applied over trunk version, revision 3761. I would like to ask the developers how much is a good time to wait for comments and revisions before commiting the changes? 1 week? 10 days? Sugestions? Edson
