- dropped build scripts and files for single-file distribution.
- updated git pre-commit hook to run "make check" instead of "make dist"
- renamed zero-input-framework to zero-input. This is to conform "there
  should be a library with the same name as package name" rule.
- rename .el.in to .el.tpl.
  melpa build process will do something on .el.in, which I do not expect.
- "make tar" is a little messy because emacs doesn't support git archive
  generated tar file.
- add zero-input-pkg.el in git, melpa build hangs when this file is not
  present.

since this is a backward incompatible change, I set version to v2.0.0.
all symbols and functions is now prefixed with zero-input.

This change is suggested by melpa reviewer.

- 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

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

added "make compile" to byte-compile and run tests in emacs batch mode.

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

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.
