Retrieve file properties

[notsolucky]

• getFiles allows for passing ReadDir options which enables users to retrieve a list of file properties instead of simply a list of names
  • the properties enable differentiation between folders and files
• an additional getProperties method allows to retrieve contentlength and contenttype meta data
  • the actual data returned is defined by the WebDAV server, nextcloud does return the above
• for nextcloud the readDir request does not return a creationdate property which is expected by npm-WebDAV-client, which will cause it throw an error
  • changes where made to the later library so that we check for the existence of a creationdate property on the response and if that fails use the modification date instead (hence we switch to tentwentyfour/npm-WebDAV-client as a dependency)
  • this might be nextcloud specific, according to rfc4918 this property should be defined
• the source needs to be recompiled

Thanks for the excellent work. Adding tests and documenting FileDetails are the only things we have left to do

I'll write tests for getFolderFileDetails and move, but I chose to leave out getProperties, because it has several important flaws: 1 - The docs are next to useless 2 - getProperties? What properties exactly are we talking about? 3 - There are no tests
