elpa: updates
init.el: change the font from Menlo to PragmataPro, delete "(setq
projectile-enable-caching t)", this makes `C-c p f/F`it works only for the cached files
init.el: comment out *modes for flyspell-prog-mode(flyspell in
comments and strings constant), unnecessary.
init.el: fix the bug ascope won't work, delete the ascope related
shortkeys sets, they're unnecessary. Enable projectile cache and make
some comments about it.
elpa: add xcscope for cscope, ascope is just an extension for xcscope
init.el: turn on syntax highlight for config files, enable
scroll-left/right when lines are too long but not wrapped
elpa: add macrostep package for debugging lisp
