CB-5093: Add versionCode and CFBundleVersion during prepare

The version can be given as part of the <widget> tag.
Example:
<widget
	id="io.cordova.hellocordova" version="0.0.1"
	android-versionCode="7"
	ios-CFBundleVersion="3.3.3"
	...

If not specified in the widget tag, the following defaults will be used.
Assuming version = "MAJOR.MINOR.PATCH-whatever"
versionCode = PATCH + MINOR * 100 + MAJOR * 10000
CFBundleVersion = "MAJOR.MINOR.PATCH"

Not adding the "other" version for windows platforms at this stage.
It's is in
Properties/AssemblyInfo.cs which we currently don't modify.
[assembly: AssemblyVersion("1.0.0.0")]

For more info about the "other" versions see:

Revert "CB-6267 Windows8. Apply BackgroundColor from config.xml"

This reverts commit 56a7893362421b49e782521698057ae40d7c8d3a.
Recreate "platforms" dir if it was deleted.

If the platforms dir is missing, cordova won't complain any longer. It will
think that no platforms are installed. The dir will be recreated when running
cordova platform add.

CB-6329 improve 'cordova info' command

info.js file has been modified to work mainly asynchronous.
Added info-utils, which contains several useful functions required by
info.js
-It doesn't require a template to set an output.
-getNode, getCordova, doPlatforms works asynchronous, works with
callbacks and deals with errors.
-it writes a report (info.txt) in rootProject.

This changes are required for futures improvements.
