- renamed zero.el back to zero-framework.el
- to build a dist, just run "make".
  the zero.el template is in zero.el.in
- zero.el is built and added to git repo in git pre-commit hook. it will
  be kept in master branch.
- fixed a few package-lint style warning.

split ert tests to separate files. These tests are not required in melpa
distribution.

- fix almost all checkdoc problems. the rest I don't know how to fix.
- add git pre-commit hook

- merge lexical-binding line with file intro line
- allow capitalize zero in some docstring/error msg
- add "make pkg" this will create tar for package.el

updated many docstring. mostly minor changes.

according to http://www.apache.org/legal/src-headers.html#headers, there
should be no copyright notice in the header.

- added zero-version variable in zero-framework.el

- handle fetch more in page down function.
- let build-candidates sync version support fetch-size param.
- adjusted some debug log
- tested zero-pinyin and sync and async mode, both works. I can't feel the
  difference.

dbus based sync and async api both works.
- added error handler for dbus client in emacs lisp.
- use lexical-binding for all files
- added M-x zero-reload-all this will byte compile and reload file files.

let zero-table base on it.

basic things work.
pagination not added yet.

this is largely working, only waiting for integration with zero-panel.
