Json write (#313)

Browse Source 
* always output latest version of config file to webui

* fix permissions after default config export

* tune code

* set permissions for exported effects

* use qt setperm instead of chmod
update effects code style a bit

* add fallback when config is not readable

* ui: when sending config, convert to utf8 to save size and avoid jumbo frames (todo: minify it)
jsonclient: add some constants for websocket frames (taken from https://github.com/zaphoyd/websocketpp/blob/master/websocketpp/frame.hpp)

* webui:
refactory of websocket connector
sended json data is always convert to utf8
