Added match() function

[joente]

Description

It would be useful to have an option to get match groups using a regular expression.

Example:

m = /version ((\d+\.?)+)/.match("This is version 3.5.1 of the program.");
m; 

Response:

[
    "version 3.5.1",
    "3.5.1",
    "1"
]

It returns an array where the first element is the full capture, followed by the capture groups.
It should return nil if no match is found.

If the regular expresstion has the g (global) flag, then an array will be returned with all matches, an empty list if no matches are found.
