Update Modulefile

bump to version 0.0.2
Update README.md

clarified install_options multiple parameter usage
https://github.com/chocolatey/puppet-chocolatey/issues/19 use chocolatey list -lo instead of version all -lo to prevent package name / version mangling
(maint) ignore .idea folder
(maint) use existing puppet/facter/hiera

If the Environment variables are set for puppet/facter/hiera,
use them instead of installing the gems for those. This is helpful
for those that work on those code bases and don't want to
constantly have to struggle with deleting facter gem when working
on the code base (facter is a special snowflake when it comes to
looking for facts along the loadpath and makes having it installed
impossible to update the code reliably).
(#19) Use List -LocalOnly

Remove findstr references as they are no longer necessary with
list command.
(maint) Remove "Reading environment variables" from packages

This removes the package "Reading" that shows up incorrectly when
parsing chocolatey output
(maint) cleanup of :chocolatey command
Merge branch 'use_list_instead'
