Implement connection settings tab
Finished settings dialog (resolves #4)

Also bumped version to 2.0 as this is one of the major changes scheduled
for that milestone.
File upload fixes #21 and #22
Fixed window captures missing out on a few pixels

Turns out it's a bug(?) in GetWindowRect when "not linked with WINVER=6"
on Vista or higher. Switched to using DwmGetWindowAttribute from
dwmapi.dll which should prove to return more accurate results for *all*
windows.
Fixed GetActiveWindowDimensions again

...in case of maximized windows
Refactor some stuff into a NativeWindow class
Fixed exception on Browse buttons
Disable WinSCP version check

Because the assembly version needs to match the exact WinSCP version,
and if you manually replace the WinSCP.dll, it will complain with
another exception. Basically, fuck this setup. Except it's the only
thing that works.
Updated WinSCPnet.dll to 5.5.5
Merge pull request #24 from horsedrowner/config-editor
