Refactoring support

[arietto]

Hello, Vadim! Thanks for you effort. Will you add any basic refactoring tools? I think that renaming (variables, methods) and changing signature are the most important and requested refactoring killer features. You can watch this video for some inspiration (concerning new IDE from JetBrains - CLion): https://www.youtube.com/watch?v=0GbMH-whqHQ Also, I like that JetBrains IDE feature - when I type variable name in the typical dialog "Add watch", I have autocomplete support even in the edit box (not just in the main editor). If I forget exact variable name in a more simple IDE, I have to close "Add watch" dialog ('cause it's modal), then find variable in the source editor, then reopen "Add watch".
