FakeVim improvements

From the feedback form:

I hope fakevim more vim features such as command input: bn: bp kind of jump
: A jump to the corresponding header file or source code, such as main.cpp -> main.h or main.h -> main.cpp switch
There ]} Jump to the next } location, Ctrl + N can be chosen to complement the next, to use their mouse to write code

I hope to integrate more vim shortcut feature that allows more powerful and easy to use fakevim
There are other functions for the time being did not expect that, if you so wish, but I'll continue to submit similar proposals that make fakevim a vim Qt development tool of choice for enthusiasts
