[Ann] helper für den Zugriff via API

bwl21

hi, ich habe einen fork von https://github.com/fodinabor/CT-API-Tools gezogen und nach meinen Wünschen und Vorstellungen angepasst.

Namespaces for Integration into other systems (Contao)
Support of API V1 (ajax) as well as API V2 (REST)
- Breaking change: It is a bit a problem that 'domain' already has the query in it.
  So I moved this into CTV1_sendRequest
- provide two request Methods CTV1_SendRequest and CTV2_SendRequest
- provide pagination CTV2_sendRequestWithPagination
Playground to play around with the API
More documentation
Improve Handling of the credentials

Vielleicht kann das jemand brauchen. Es steht im develop branch.
