* add disableEscape parameter to disable this functionality

* proper JSDoc
- FileList is now an instantiable class
- FileActions is now in namespace
- added App class for trashbin app
- moved trashbin overrides into classes extending FileList
- replaced many static calls with "this." or "self." to make the classes
reusable/extendable
- new URL parameter "view" to specify which view is shown, for example
"files" or "trashbin"
- added OC.Util.History utility class in core for handling history
- moved URL handling/routing to OCA.Files.App
- popstate will correctly update the current view and notify the view of
the URL change so it can update the current dir
- added JS unitt tests for the trashbin app
- fixed public app to work with the new namespaces
The file selection is now based on the internal model array
FileList.files instead of the visible checkboxes.
This makes it possible to virtually select files that haven't been
rendered yet (select all, then deselect a visible one)
Added more unit tests for selection (with shift and ctrl as well)
- moved the summary code into a new class FileSummary
- FileSummary is calculated only once, then updated with add/remove
- added new OC.Util namespace for JS utility functions
