Support evil

``` elisp
  (evil-record-macro 113)
  (command1)
  (command2)
  (command3)
  (evil-record-macro nil)
```

Maybe refactor to introduce `elmacro-macro-regexps` with pairs like `"(evil-record-macro \d+)" . "(evil-record-macro nil)"` 

Given we have a register, maybe `defun elmacro-show-evil-macro (register)` makes sense here.
