extended normal mode command

[yarbelk]

How should we implement the extended normal mode commands

(eg - compositions and arguments to commands)

2fd -> go to the second 'd' to the right

dt' -> delete until the '

Vi has a timeout on these, which lends itself to using a switch statement on channels. implementing the timeout first seems like overkill: I think implementing it the same way kisielk has implemented the count would allow us to get it up and running faster, and then we can refactor.

Some of these seem to be better written as functional compositions of visual, movement and normal (dt') -> d(t') ~> d(vt')

but implementing the simplest catagory - arguments to a command is probably the easiest first step.

mode/textobject.go does this by accepting range function argument and executing it after text object is fully defined on mode exit. This is used by 'd' command in mode/normal.go
