mikutter 4.0

Major version up after five and half years after prevous update,
for 10 years aniversary of mikutter, with some incompatible changes.

* make Twitter plugins third party plugins
 * Twitter plugins are no longer included
 * users can still use Twitter on mikutter by installing Twitter plugins
   https://github.com/mikutter/twitter_bootstrap
* remove Service module
 * Abstraction by Service was not sufficient and it has been replaced
   by World plugin
* deprecate boot events
 * initialization should be implemented in plugin context or
   Delayer.new {...} should be used if it need to be executed after
   load is conplete
* remove miquire
 * miquire was introduce to avoid (no-longer-recallable) problems
   on ruby 1.8 and to switch loaded files by command line options,
   but both of them no longer exist
* use own implementation to handle event loop
 * mikutter used Gtk mailloop and Delayer queue but it caused FiberError
   exceptions and the FiberError was hard to fix per specification
* make it possible to change, preserve and restore order of general
  Model viewer tabs
 * orders of tabs in Mastdon user prifile tabs are recoreded and
   preserved on the next open even on other similar tabs
* support Ruby 2.5 and later (drop support for 2.4)
 * ruby 2.4 will be EOLed on end of March 2020
   https://www.ruby-lang.org/ja/news/2019/10/02/ruby-2-4-9-released/
* drop bundling gems in release tar ball
 * nowadays bundler is common enough and plugins with Gemfile made
   things more complicated
* all other things forgotten to be written
 * all things I missed
