Generalize syntax

[JohnnyMalmberg]

• The "<system @ chat> message" syntax has been extended in a few ways:
• " args" will run a fictionscript called "foo" if one can be found in the current scope or the (base) > fic scope (automatically loaded from the fic and .fic folders on startup)
• "<method @ target> args" has 2 behaviors:
• • If target is a scope, and "method" is the name of a fictionscript within that scope, method will be run in that scope with those args
• • If target is a python object with a method called "sm_{method}", that method will be called, with the given args
• Fictionscript arguments are not just literal strings now; an arg that has a name starting with ":" will accept a string literal.
• There are now 2 ways to enter multi-line messages in the CLI and fictionscripts:
• • "---" at the end of the first line, and "--" at the end of the block, or
• • "--" at the end of each line until the last line in the block
• There are now for and while loops, and if statements can have multiple lines in their "then" and "else" clauses
• Moved summon.fic into the public fic folder
