--------------- step 1 --------------------------------------
removed _samples directory

--------------- step 2 --------------------------------------
-added aspell as plugin, as it is not available by default anymore.
 phpgwapi/js/ckeditor/plugins/aspell
-as aspell integration was done for CKEditor3; integration into CKEditor 4 needs
	- most lang stuff had to be loaded from other sources
	- own icon, modified plugin.js, removed aspell.css, modified dialogs/aspell.js
-changed phpgwapi/js/ckeditor3/plugins/aspell/spellerpages/server-scripts/spellchecker.php
 to allow only configured aspell, tmp dirs and language settings
-removed other than php spellchecker pages from phpgwapi/js/ckeditor3/plugins/aspell/spellerpages/server-scripts/
-added toolbar options to reflect the use/change of calls of SpellCheck(er) via toolbar button
-added an availability check on dicts (see below)
