Syncing fixes

Finnally some update from me. In this commit I mainly focused at fixes
what Ertzel requested.

So here is what I did:
- Fixed syncing between editors and server (but I think that Tilesets
are still not syncing properly)
- Finished client side part of rewrite to ReadAllProperties and
WriteAllProperties
- Fixed client side map overlay rendering
- Fixed ErrorHandler class and initialized it in server
- Added new ColorARGB class to IHProspekt.Utillities. This is basically
holder for ARGB color
- Fixed some syncing bugs between server and client (Ertzel please, when
you add something, test it also in Client, not only in Editors, becouse
Client side was totally broken lol)

Things what needs to be finished:
- Client side map and tileset data receiving (for some reason it is
receiving almost blank map)
