Started with file api, simple skeleton in place.
Started playing civetweb http embedded server.
Now have working downloading with files between 2 peers.
Removed stuff before uploading to master.
Fixed so that everything compiles with added libraries for file_server
Simplified FileServer, cleaned up CMakeLists.txt.
Remove redundant comment
Merge remote-tracking branch 'origin/fileapi' into p24_integration

Conflicts:
	api/CMakeLists.txt
stash merge conflict, fixed.
Merge remote-tracking branch 'origin/master' into rpc-functions

Needed for access to file api.
Now starts a file server at the same time as api server.
downloadFile kind of works now.
