Beta 17:

* removed duplicate "none" in filter list
* RTD also missed address error check
* MMU emulation bus error handler uses C++ exceptions again (like in original Aranym version), removed some not so useful forced inlining, smaller executable.
* decided to disable some MMU table caching and suddenly NetBSD crash disappeared, MMU emulation is probably much slower now but at least it seems to work until proper fix is found, (hopefully Aranym developers have some ideas) Debian 68k Sarge Linux confirmed working now
* right border color "glitch" when waiting for hpos<7 in copper list broke in b3
* only disable Direct3D9Ex if pixel shader support is < 2.0
* do not open files smaller than blocksize (512 bytes) as a hardfile
* hardfile dialog accepts dragged and dropped files
