Breaking: #83 - Add Pagination to Controller

See Issue #83

Description

Because in TYPO3 v11 no pagination in the frontend and backend is possible without an own ViewHelper or an extension, the list action in the Backend/CompanyController and Backend/ContactController was extended by the pagination. Via TypoScript it can be defined how many companies and contacts should be displayed per page.

Integration

An example was implemented for the list view templates.
