Support additional syntax highlighting for few OCaml tools in Visual Studio Code.

Additionally, it provides few snippets for these same file types.

This extension requires the extension OCaml and Reason IDE for formatting Ocaml code.

This extension provides additional syntax highlighting for OCaml and related tools:

• ocp-build by OCaml PRO (.ocp)
• Ocamllex (.mll)
• Ocamlyacc (.mly)

Snippets for .ocp:

• program
• library
• test

• .ocp Files:
  • begin / end block inside a list of files is not properly highlighted
• .mll Files:
  • Comments not properly highlighted
  • Top-Level curly brackets cannot be collapsed / expanded
• .mly Files:
  • Comments strangely highlighted sometimes in the rules

The grammar syntaxes for .mll and .mly came from the deprecated extension vscode-ocaml, with some modifications for OCamlyacc (.mly).
