def _get_component_name(self):

Since this is just an arbitrary name used by the client side code, we should add an option to customise these. Possible solutions:

• define the prefix cmp in the settings (probably this is enough for most use cases)
• specify the names for each fieldtype manually in a settings dict or similar
• do nothing and let the user overwrite the function every time he want's to have a custom name

There are several other usages of the cmp prefix in the project.
