Add support for companies CRM API calls

This allows using company scoped API calls. It's basically copy paste from contacts. The companies default properties are not complete so not sure if people feel that this should not be merged as is. I unfortunately don't have the time to work on it further so wanted to propose to merge it.

Thank you @joidegn
We understood the demand for the Company API and wanted to implement it.
It's okay to merge in between, but I'm going to check the default properties before creating the version. (Therefore, you may have to wait for a while)
