user can toggle full-width mode via C-c , .
or they can set zero-full-width-mode in buffer or use setq-default to
set default value for all buffers.

updated the way keymap is configured.
switch to C-c , prefix according to minor-mode keybinding convention.

so that user can bind any key to them.

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

in emacs 25+, now it's accurate when tool-bar, menu-bar is enabled.
in emacs 24 or lower, tool-bar, menu-bar are not well supported.

`case' is from cl;
missing `take', `drop' added as local functions.

in ShowCandidates(), replace the Move() dbus call.

now user typed phrases will be saved.

minor update on some debug message.

- this is more robust than remembering major mode's binding and do
  dispatch.
- add :preedit-start and :preedit-end slot function, so IM can add key
  map for preediting state too.
- bugfix: should ways use zero-set-state to set state.
  updated one set in define-minor-mode

- zero-framework.el add support for :shutdown function
- bugfix: zero-backspace-original-func check for nil before setq
- update zero-pinyin-service client, service is renamed

- zero-framework.el and zero-pinyin.el when updating zero-fetch-size,
  should update it to

    (max (length candidates) fetch-size)

  because service can return more than asked and it still counts.

- zero-panel.el add hints support and use it for pass has_next_page,
  has_previous_page indicator.

- 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.

replaced the command remap for delete-backward-char.
because some major mode bind DEL on other command.
zero-mode should always allow DEL for preedit-str editing.

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.

easier to read and eaiser to write.

make partial commit work with zero-pinyin.el
added a few "virtual functions" in zero-framework.el
removed SPC key in keymap, just use self-insert-command remap.

add auto commit first candidate or preedit str on punctuation insert.
add default binding C-. for zero-cycle-punctuation-level

let zero-table base on it.

basic things work.
pagination not added yet.

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