'''$regsub([name], text, re, subtext, %var)'''

Performs a regular expression match, like [[$regex|$regex()]], and then performs a substitution using subtext.<br />
Returns N, the number of substitutions made, and assigns the result to %var.

Example:
 alias testing {
  var %num_of_matches = $regsub(a dog was eating milk,/dog/g,cat,%new_content)
  ;%num_of_matches will have a value of 1, since 'dog' was matched once
  ;%new_content will be 'a cat was eating milk'
 }
