Convert LWRPs to custom resources

[damacus]

:person_frowning: Problem Statement

Custom resources have a number of benefits including simpler syntax. We will be able to provide resources with multiple names for backwards compatibility and support the new naming format as per #775

:grey_question: Possible Solution

All resources in the libraries folder are converted to custom resources.
