Path syntax addition

[Victorious3]

In light of potentially using Princess as a shell replacement it would make sense to have something as crucial as paths and their manipulation as a language feature.

It could work like this:

let segment = "folder name"
let p1 = ./some_path/{segment}/more_path/
let p2 = #/root/path/{p1}/../up
let p3 = ./some_path/{segment}
let p4 = ./some\ path\ with\ spaces/
let p5 = ./"how about this"/instead
let p6 = ~/relative/to/home

Paths may be concatinated with other paths or alternatively strings directly.
A path would be introduced by either a unary #/ for absolute paths, ~/ for paths relative to the home directory or a ./ for paths relative to the current working directory.
The path ends with a space or alternatively a closing /.

Additonally one could support globs as part of paths:

for var p in ./some/path/*.txt {
    print(p)
}

These would return a special Glob structure instead of a Path.
