* Fix eslint errors on Windows
On Windows, when run `npm run lint`, a **LOT** of the following errors
appeared:
```
error Expected linebreaks to be 'LF' but found 'CRLF' linebreak-style
```
This error only occurs on Windows because the `linebreak-style` eslint
setting was set to "unix". This is fixed by making the eslint config
file a Javascript script and setting the platform based on the build
platform.
Thus, the `linebreak-style` will be "windows" or "unix" depending on the
users platform.
* Remove linespace ending check in Lint
Add .gitattributes that will convert line endings automatically to LF when uploading to GitHub
* Remove bat file extension from gitattributes
Include lint check for line endings
* Change tabs to spaces
* Force LF line endings for each file upon downloading
Restore eslint linebreak style check for unix since LF line endings will be enforced
* Add a few more text files to the gitattributes
* Added png as binary file to gitattributes file
This was necessary because git was showing that the CRLF line endings were being converted to LF for PNG files on Windows
