add preview bar template for edit button and more
change bIsPreview to be instance var

made this only local so far, because moving it to PageTypeModule would create problems with other plugins

and
• added method renderJournalEntry that can be called from javascript in order to update entries
• added preview bar in preview mode
refactored handle_preview for preview editing

basic editing of journal entries, reloading entry on save
added styles for preview edit button

the button is actually the one used in admin
I left it this way because somehow I like it and lets discuss this eventually
Make sure preview only instanciates stuff once
Update to latest base
fix manager in link to detail
fix preview links and queries

• make sure that all links work for preview too
• display inactive journal entries in preview
Merge branch 'preview-editing' of github.com:rapila/plugin-journal into preview-editing
removed deprecated PublishedAtDisabled variable

the published_at input is only disabled if the journal_entry is published, any other calculation is nice, but too complex.
the content managers have to know what they do if they change the published_at input after having published it.
(note: permalink is made with the published_at date)
Replace PublishedAtDisabled value by IsPublished
