Functions system (advanced macros)

[LeafHacker]

The idea of macros supporting advanced logic has been discussed before. I'm in favour of an approach that doesn't tie this too closely to the keybind/macro system and is instead more general.

My proposal is a Functions system.

• Functions are written to the Impact/functions/ directory
• The filename acts as a name/id for reference within the client.
• The file may contain a list of lines to be sent to chat
• There may be a parser to handle logical syntax, or if possible logical commands may be added to the command system instead.
  • Adding commands instead of function syntax has the advantage of being usable even when typing directly into chat. Think .# to comment, .if to branch .test for boolean statements, etc... Inspired by shells such as sh, bash, zsh, powerline, etc.
• "anonymous" functions may be possible too by having a command that parses and then runs a function.
• Functions could read arguments either as an argc/argv list or as $1,$2,etc globals.

This idea would replace advanced macros, since a macro could simply run a function.
