core: improve the string_replace_regex function (add reference char, change syntax for match refs)

Browse Source 
The reference char is now an argument for the function.
The references are now $0 .. $99 and $+ was added (last match, with
highest number).
The syntax to replace a match with one char is now: $.cN or $.c+
(for example: "$.*3").
