[Issue #64] Fix the minibuffer bug on 24.3.xy emacs builds
Use sp-recent-keys instead of this-single-command-keys
changed default pair for "`" from "'" to "`"
removed special cases for "``" pairing as it is default now
added exceptions for lisp and TeX modes, those still need "`'" pairs.
Merge pull request #75 from vderyagin/backticks

Made backtick pair with itself, except in lisp and TeX modes
Update tests to reflect the `` pair change
Fix infinite loop with cua-mode and selection replacement with closing pair character
Merge branch 'master' into test-mb-password
