fix(config): selective cfg write;fix cfg parser
* config parser now handles quoted values correctly. This doesn't hamper multi-line support.* added regression test to travis to assure we will be warned if we rewrite and break the user's .gitconfig file* only rewrite configuration files if we actually called a mutating method on the writer. Previously it would always rewrite it.Fixesgitpython-developers#285
