* Target VimL upstream .sublime-syntax file
Upstream **VimL Syntax** has been updated
to include `.sublime-syntax` file instead of `.tmLanguage`,
therefore manually added `.sublime-syntax` is no longer needed
* Remove .bin changes
**NOTES:**
- PR is not yet merged in upstream repository (https://github.com/SalGnt/Sublime-VimL/pull/12),
but sublime-syntax file is already updated with changes.
- Updated syntax test files are added as well
This fixes#1064
Adds a syntax highlighting test for VimL
with source file based on parts of my own configuration
changed to cover as much of syntax as possible.
**NOTES:**
Last line of source (`syntax enable`) does not get highlighted,
since `syntax` keyword is not part of highlighting rules.
