Cherokee tweak

[FIXED] The change in server.c should be really evaluated, the code gets in a deadlock.

I also hope someone could come up with a better parser of the command line arguments in cherokee-tweak. Due to the increasing number of issues with cherokee-tweak/handler_admin I don't have a clue what exactly fixed #750, but it does rotate now with and without authentication.

Additionally I would like to see verified that none of the serialisation formats actually require that forward slash should be escaped. That includes: php, ruby, python and json, if so the follow commit should be replaced by something that removes the entire adition of "\/".
