Support dot notation in variable names

[fredriks]

import?abc.def.ghi=>1 => var abc = {}; abc.def = {}; abc.def.ghi = 1;

import?window.jQuery=jquery => var window = {}; window.jQuery = require("jquery");

Fixes #28, fixes #22, fixes #32

Does this PR handle case of injecting multiple globals? For example: import?window.jQuery=jquery,window._=lodash

@korya It does handle multiple globals on window. I've added tests that illustrate various cases.

Great! Thanks!

@sokra What do you think? can it be merged?

It looks like this code change may override some variables which are already exist. For example i have global / local variable noty.

import?noty.theme

will be compiled to

var noty = {};
var noty.theme = __webpack_require__(XXX);

which will override my global / local variable noty that can be used in code

@fredriks, looks like @artyomtrityak is right (disclaimer: I'm looking purely at the code). At the moment you have a specific check for var window (window || {}), perhaps that could be changed so it works on all variables?

[fredriks]

Aye, good point! I'll update the PR with a more general approach.

[artyomtrityak]

looks good for me

[SpaceK33z]

Thanks a lot @fredriks!
