What's new in this release?

- Lot of bugs were fixed.
- Local variable renaming now has highlighting over actual variable instances to be renamed. As a reminder, actual variable instances mean that only variable instances of the same type with the same name in the same scope. For example, a user may see two variables, `A::var_1` and `B::var_1` with the same name and the same type, but only `A::var_1` is highlighted when renaming and `B::var_1` is not highlighted, because the one highlighted is in the same scope as the variable user chose to rename.
- Improve getter/setter generation:

  + Users can specify a regexp to remove a part of variable name such as prefixes like "m_" or "_".
  + Users can capitalize the first character of variable name in getter/setter with `srefactor--getter-setter-capitalize-p`. So, user can combine with `srefactor--getter-prefix ` and `srefactor--setter-prefix` to generate getters and setters like `get_Age` or `getAge` or `set_age` or `setAge`.
  + Allows getter/setter to be inserted in other file (file with the same name but different extension).

- Add initial support for Emacs Lisp refactoring with code formatting (not just indentation). See buffer formatting and one line/multiple line transformation demo: https://github.com/tuhdo/semantic-refactor/blob/master/srefactor-demos/demos-elisp.org.
