Prepare for GNU ELPA release

* Transfer copyright to Free Software Foundation
* Add packaging components (e.g. headers)
* Coding style fixes:
  + Quote functions with "#'"
  + Wrap long lines
  + Fix doc strings / comments
* Replace `string-to-int' with `string-to-number'
* Fix compiling errors / eliminate compiling warnings
  + Add exwm-core.el to hold common variables, functions and macros
* Remove the redundant COPYING file
* Add .gitignore
* Rename README to README.md
