Micro 2.0.3

This is a relatively minor update. For the next large update (2.1.0) I hope to provide improvements to the keybinding system and a (light and optional) Vim keybinding plugin.

v2.0.3 changelog:

• Micro will output to pipes if it is on the left side of a pipe
  • Running micro | cat will open micro and pipe the result (when the buffer is closed) to cat. Since micro can also read from pipes, this means you can make a pipe chain interactive by placing micro in it.
• New +LINE:COL flag for opening a file at a location (file.txt:LINE:COL syntax still supported)
• Minor bug fixes
• Syntax file improvements
  • Csharp-script (new)
  • Sagemath (new)
  • Julia
  • Python 3
• Linter improvements
  • Haskell
  • C++
