GPII-94: Update GPII to run on Node 0.10.29 on Windows

http://issues.gpii.net/browse/GPII-94

I have made the following changes:

- Updated node_modules/ffi to 1.2.7
- Updated node_modules/ref to 0.3.2
- Updated node_modules/ref-struct to 0.0.6
- Updated node_modules/bindings to 1.2.1
- Updated node_modules/debug to 1.0.4
- Removed the duplicate debug and bindings modules
- Removed the unnecessary *.tlog files
- Updated GPII to use the new ffi and ref modules
- Corrected the pvParam type for SystemParametersInfoW SPI_?ETMOUSETRAILS actions -- UINT rather than BOOL (see http://msdn.microsoft.com/en-us/library/windows/desktop/ms724947%28v=vs.85%29.aspx)
- Converted spiSettingsHandler/ line endings to Unix

The conversion of the line endings makes it hard to see my SpiSettingsHandler changes on GitHub. Locally you can see the changes without the line ending change noise with:

git diff --ignore-space-at-eol master GPII-94 -- gpii

(or git difftool ... if you have a difftool set up)
