[WIP] [feature] StructureBracesFixer

Braces for structure blocks, fix #98

- [x] add missing braces
- [x] correct single-level intend
- [ ] correct multi-level intend
- [ ] fix #168 
- [ ] `endif` ect tokens
- [ ] make Travis pass
All this loop is the same than ``$tokens->findBracesBlockEnd`` but using parenthesis instead of braces. I suggest making ``findBracesBlockEnd`` able to handle both cases instead
