Initial Update of Windows Packaging (#438)

* Update run.py & .gitignore for windows

- Update run.py to execute on windows as SIGQUIT is not available.
- Update .gitignore to ignore the generate .pyd files
Ref #300, #393

* Update package.py for windows

Add package_windows back into package.py
- Using cx_freeze for freezing installation
- Will be using nsis for actual installer
Tested with python 3.5 64bit on windows 10
Ref #393

* Update makefile for windows (+2 misc)

- Update the makefile to support windows
- Use different bin path in virtualenv
- Use pyd instead of so files
- Tested with Msys2
- Add *.exe to .gitignore
- Fix minor format error in package.py
Ref #393

* Add requirements-windows

Add the requirements-windows.txt
- contains cx-Freeze for bundling
Ref #393

* Add initial setup.nsi

Initial Version of a NSIS installer script
- Multi-user install (install for just one or all)
- Registers uninstaller (more values need to finish up)
- Tested both single and all install / uninstall and works
- Still need to add parameters instead of hardcoded values in some spots
- Need to clean up vendor folders / keys if empty on uninstall
- Need to add the other dupeGuru languages to the language list
- Minor cleanup of script needed as well
Ref #393

* Update setup.nsi

Updates to setup.nsi including:
- Defines from CLI
- Version information (MAJOR, MINOR, PATCH)
- Bits (64 / 32)
- SourcePath (if we wanted something other than build)
- Added extra defines to move application specifics to one location
- Added extra defines for uninstall information
- Added calculation of install size
- Added switching between 64 and 32 bit contexts (need to verify
functionality)
- Updated output file naming
- Added NSIS supported languages which are also supported by dupeGuru
- Added rest of registry keys for uninstall information
- Added missing registry key for installType
- Added removeing Vendor folder and registry key if empty on uninstall

Should be very close to having this installer script ready to integrate
into the package.py script if desired.
Ref #393

* Update README & requirements-windows

Minor update to README to indicate windows is supported.  Add PyQt5 to
requirements-windows.txt to make installation easier.

* Update packaging for windows

- Update package.py to integrate NSIS for windows
- Update makefile to deal with a few additional windows issues
- Add Windows.md to contain specific windows instructions, if we want
this can be merged with README.md
- Minor formatting update to setup.nsi
Ref #393

* Update README & Windows Instructions

- Update the README to include a reference to the Windows instructions.
-  Add some additional notes into Windows Instructions and remove one
incorrect command.
- Update .gitignore to ignore all permutations of env* to allow for
multiple side by side virtual environments (used to build different
versions for windows)
Ref:  #393

* Update Window.md

Fix broken python link and move nsis link for consistency.

* More Details in Windows.md

Update Windows.md including:
- Information on compilier requirements for windows
- Notes about the windows 10 sdk
- Some clarification around some of the steps
- Addition of msys2 links

Going to review this a bit more to polish it up.
