Basic bugs with connection

Map wasn't sent, fog alpha not defaulted to assume full hiding, and
other dumb things.
Perf increase for Graphics

Sparks found the magic combination of Interpolation and Smoothing modes
to allow for quick scrolling while zooming.
Connection perf fix, simplified Center Map img
Merging in sparks' stuff as possible

Picked out the things that made sense to include, and ignored the stuff
that didn't fit the newer design. Doesn't include the cool fog effect,
which I'll try later.
Removed PictureBox altogether

Unnecessary additional control. Using just the UserControl instance
itself now.
Merged in neat Fog Effect + setting to toggle

Merged in work from Sparks on getting a fancy Alpha Fog Effect. Added a
setting in case it's not a good hit, but it looks awesome albeit reveals
a little too much with the alpha... Will look into that at some pt.
