Code review comment for lp:~sil/enso/platform-specific-folders

Provide extra interfaces for platform specific stuff.

If you want the folder where commands are stored, call:

from enso.providers import getInterface
getInterface("scripts_folder")

and there are now two new interfaces:

getInterface("learned_commands_folder")
getInterface("data_folder")

The ensoapi object now also provides a get_enso_learned_commands_folder so the learned-commands folder is available to commands.

Neither of these interfaces are currently used, but we need to build a "learn as open" command which is cross-platform, and that will use "learned_commands_folder".

Please confirm that this works on other platforms; I can confirm it works on Linux. Note that I may have *moved* the folder to somewhere more appropriate, which could mean that all your existing commands may need to be moved. Install the Enso Developers command from http://www.kryogenix.org/code/enso/ to easily find out where your installed commands are.
