* allows to add a new tagname hitting enter
see: https://groups.google.com/forum/#!topic/tiddlywiki/wqQ8jPYG-X4
* revert changes to vanilla/base
* added "Special Keys" to KeyboardShortcuts
* added info to Creating and editing tiddlers
did not add current version of <<.from-version "5.1.14">> because it
would interrupt the flow. When changed from a noisy "New in 5.1.14" to
"(new in 5.1.14)" we might add the version info here
* revert setText & added inline styles to vanilla base
* remove fieldmangler
* commit initial edittemplate tags to merge master
* ok, now really revert to initial edittemplate tags
* move add tag via enter into tag-picker macro(s)
