The new behavior is as follows:

IF a user has a token and `features` is not set, we treat it as if the
feature was enabled.

IF a user has a token and `features` is set, we check if the feature
name has a value of "true".

`isJwtFeatureEnabled` also provides a way to specify the default value
in case there is no token.

- add possibility to allow execution of the button's routine besides triggering
`toolbarButtonClicked` API event
- keep backwards compatibility
- get rid of `ToolbarButton`
