Rewrite using sublime-syntax format

[13xforever]

Sublime Text 3 has been released, and with it comes support for a new, more robust syntax highlighting definitions.

There's also a new documentation on recommended scope naming conventions.

This is really exciting, as it comes with more advanced features such as context stack and syntax testing facility. This allows for more modular and reusable syntax definition with less complexity and more breakage control.

• [x] Complete rewrite of the syntax definition, following more closely to NASM docs
  • [x] General syntax
  • [x] Pseudo-Instructions
  • [x] Constants
  • [x] Expressions
  • [x] Labels
  • [x] seg, wrt, etc.
  • [x] Preprocessor
  • [x] Single-Line Macros
  • [x] String Manipulation in Macros
  • [x] Multi-Line Macros: %macro
  • [x] Conditional Assembly
  • [x] Preprocessor Loops: %rep
  • [x] Source Files and Dependencies
  • [x] The Context Stack
  • [x] Stack Relative Preprocessor Directives
  • [x] User-Defined Errors: %error, %warning, %fatal
  • [x] Other Preprocessor Directives
  • [x] Standard Macros
  • [x] Standard Macro Packages
  • [x] altreg: Alternate Register Names
  • [x] smartalign: Smart ALIGN Macro
  • [x] fp: Floating-point macros
  • [x] ifunc: Integer functions
  • [x] Assembler Directives

And we're mostly done with the preprocessor stuff (still need to fix the illegal declarations for %assign)

The bad news is there's no way to autoconvert sublime-syntax back to tmLanguage. Well, this sucks.

As of 7acaea9 I deem this rewrite to be feature-complete

Moved additional tasks to separate issues
