Make Services accept/reject all in selection.

[achabotl]

Replaced the addition, deletion and substitution regular expression searches with substitutions and I daisy chained the outputs of the substitutions. This means that it's not longer necessary to select only the critic markup section; it's possible to select any text, as long as it contains the markup to accept/reject.

It's now possible to select a section with multiple edits, even the whole document and "accept all" or "reject all".
