There’s some situation when there are only one option and that displays
“All selected” which is only correct if the select tag is “multiple”.
In using this plugin for “single” dropdowns as well, there are
situations when there’s only one option and it shouldn’t show “All
selected”. This fixes that

Added option for #466 - although this may be handled easier by directly modifying the buttonText option!

Created an inheritClasses option (default: false) that pulls classes (documentation still to be done).

Change dataprovider tags variable into an array instead of jquery object to keep order of dataprovider array. Got rid of .add() as jquery states:

http://api.jquery.com/add/
"Do not assume that this method appends the elements to the existing collection in the order they are passed to the .add() method"

Improves the initialization of the multiselect by waiting for other select related bindings to finish first.
Moved the subscription to other binder events to init so they aren't re-executed all the time.
Added support for value binding.
Added support for observable configuration properties.
Observable subscription rate-limited (by @IDisposable).
Simplified how selection changes are processed (simpler code, not sure about performance).

-> Added setAllSelectedText function to set the text displayed when all options are selected dynamically at runtime
-> Updated doc
