Cygwin: cygcheck: package info / available package search, take 2

- if the user has no perms to write to /etc/setup, don't try
  to fetch user homedir from Cygwin (crashes galore).  Use
  LOCALAPPDATA path instead.
- info is more rpm like
- print info of installed package
- added info selectors --inst, --curr, --prev, --test
- add installation date

TODO:

- Human-readable filesize
- url and license needs to be added to setup.ini yet
-
