Fixed bug where RPC was not registered correctly when
LazyLoadComponentProvider was used.
Added/fixed: 
- fixed LazyLoadComponentProvider bug
- fixed proximity and visibility checks for Vertical position (disabled
horiz-checks as they are probably broken)
- added debug mode to print positioning and visibility check information
to VConsole
- fixed server-side lazy load reinit to add the LLW back to the poller
for future updates
