Create modular structure to define states

[felquis]

Related to #13

The pattern is easy.

starter -> application name
starter.state -> app's states
starter.state.sidemenu -> Define sidemenu state
starter.state.search -> Define search state
starter.state.search.controller -> Search Controller
starter.state.sidemenu.controller -> Sidemenu Controller

All the files are listed in js/load.js and all the modules are associated in js/app.js
