Disable the `replace()` when the selected `CodeMirror` is `readOnly`.

Bumping them for every release just adds too much git
noise and history blowup.

The vim mode was making sensible use of a searchcursor with
a match-everything regexp as cursor.

Issue #1870

The variable "query" only contains the string version of the query, even if a regex has been submitted. "state.query" contains either a regex object or a string, depending on the input.
The function searchOverlay contains the neccessary logic to differientiate between these two types, indicating that the original purpose of it was that regexes should be highlighted accordingly.
Passing the "query" variable to searchOverlay fails to highlight regexes, for example case insensitive searches, and thus isn't in sync with the find next / find previous commands.

Rather than polluting the top-level of the editor object

This helps performance on v8 (in microbenchmarks) and is less noisy.

Regular literals are still accepted, the constructor is only used to create
objects, doesn't attach any methods.

For cheaply adding extra styling without going over
the whole document and doing markText.

Issue #1069

As spotted by the extended linter.

Things that happen in a single operation are now always combined into
an undo history event. Subsequent typing or deleting is combined, if
it is close together in time, even when done in separate operations.

Closes #889

Also stores old selection position in undo history, restoring it
when applying a changeset.

Issue #923

The class is now specified as an option, rather than a separate argument
(and is thus optional).

Incompatible API change.
