jscs: exclude file in config quick fix (not ideal implementation though)
(cherry picked from commit 73e628c)
jscs: do not call JSCS for analysis, if file is excluded in config (since we copy files in tmp directory if they are changed and do not keep structure, excluded file can became not excluded + it is just unneeded operation)
(cherry picked from commit 632f64a)
jscs: add file to excluded list: do not use text generation, to use only psi
(cherry picked from commit eb95b25)
backspace handler, extract brace matching
(cherry picked from commit 3608bca)
