Inquire the backend for device capabilities instead of Web UI assumptions (#688)

* Add capabilities to RaCtlCmds.get_device_types() to return the image file support boolean, and list of supported block sizes.

* Inquire rascsi backend about the min block size rather than hard coding values in the web UI.

* Add class methods for getting lists of certain device types.

* Use the new class methods to get lists of device types in the web ui.

* Make use of the new class methods in the oled script.

* Remove now unused constants, and simplify logic in common_settings

* Improve device name mapping to extend the existing dictionary rather than creating a new data structure.

* Use jinja2 sort filters instead of sorting in python code. Removing redundant variables.

* Introduce the get_device_name() utility method which returns the translated name for a device acronym. Use the new method to display device name when attaching devices.

* Fix typo

* Rename Support Device to Periperal Device. General tweaks to UI strings.

* Tweak UI string.

* Fix error.
