paredit.el version 26

Minor bug fix release, mainly to set a new branch scheme:

- `master' branch is where development and releases happen
  => on release, one commit to remove beta and a second to bump version
- `release' branch points at latest release commit on master
- no `maint-N' branches

This replaces the old scheme where master was branched into maint-N and
then the beta tag was stripped off in the maint-N branch, which meant
no one branch would automatically track the current release as ELPA
prefers.

Other changes:

* M-s (paredit-splice-sexp) now restores column in text fields like ielm.
* Deletion now respects `delete-active-region'.
