Fix checking for allowed tag hierarchy for tables. The way, the check is
currently done (not transitive), the tag hierarchy for table related tags
(td, th, tr) has to be set to 'div' to enable inserting tables into
editables that are themselves contained in non-editable tables.
IE default drag and drop behavior is stopped when dragging and dropping
block elements.

In some cases the default IE drag and drop behavior was not stopped for
blocks, so dragging and dropping blocks messed up the content. The root
of the problem was a Javascript Error (rangy-core) when dragging the
element. This error was thrown due to a bug in the IE selection. With
this fix the IE default drag and drop behavior is stopped and the
Javascript Error is catch, so the excution of the program can continue.

Setting sanitize contenthandler configuration as a Map is load.

If a configuration in Aloha.settings.contenthandler.sanitize was defined, this was never load unless
was a text ('restricted', 'basic', 'relaxed'). If a map of object was defined, this setting was
never load (see http://aloha-editor.org/guides/plugin_contenthandler.html).
With this fix, the sanitize object is load.

Fix checking for allowed tag hierarchy for tables. The way, the check is
drag&drop: Dragging and dropping a table inside another table is not permitted.

Nested table are forbidden, but dragging and dropping tables inside tables were permitted. With this fix this behavior is not allowed anymore.
