    I'd rather not to pass `this` reference to this method, especially if the only thing we
need is a couple of properties from 'locations' object (`this.locations.platformWww` and `this.locations.www`
at L120). Maybe just pass these properties as an arguments, or revert to previous signature?

> Many cordova CLI commands include a "prepare" operation, including 'cordova build', 'cordova
run', 'cordova plugin add', and more. Every time each of those commands runs, the target platform
is "prepared", which involves copying all files from the [<project>/www, <project>/platforms/<platform>/platform_www,
<project>/merges/<platform>] to the platform's target www folder, as well as copying
a bunch of icons and splash screens to platform-specific locations.
> For the very first prepare of a platform, all that file copying is necessary. But most
of the time after that most of the files being copied have not changed and therefore don't
really need to be copied again. So the typical developer inner loop (edit a few source files,
build and run the app, repeat) is a lot slower than it could be for a Cordova project, especially
one that includes a significant number of source files or resources.
> Instead, Cordova should be smart enough to skip copying of files that haven't changed,
based on their last-modified timestamp. (But also there should still be a way to force a clean/full/non-incremental
build if desired.)
