Merge pull request #1219 from pypa/add-ci

* update detecting Windows Python installations

- now correctly detects current user installation and not just
  those installed at the system level
- for Python versions 3.5+ (which track 32-bit & 64-bit installations
  separately), recognize version tags X.Y, X.Y-32 & X.Y-64 where X.Y
  represents the 64-bit installation if available or 32-bit otherwise

* touch up & improve `resolve_interpreter()` tests

- tests no longer permanently modify the `virtualenv` module under test
  (`virtualenv.is_executable` changes were leaking from some tests)
- tests now check that `get_installed_python()` results unrelated to the
  given version tag do not affect the result
- simple patch function's return values now given in `@patch` decorators
  to make the test code more compact

* test resolve_interpreter() with registered python installations

* test `get_installed_pythons()` on and off Windows platform

* add embed tox env

* disable Python 3.4

* fix coverage reporter
