Fixed issue #11
Fixed issue #12
AHI now checks that Interception.dll exists, and also checks that it's bitness (x86 / x64) matches that of AHK.
Appropriate errors are now displayed.
Big improvement to the handling of "Extended" keys (Right variants of keys etc).
The "Extended Shift" that gets sent when one of these keys changes state will no longer trigger Context Mode, or trigger subscriptions to Extended keys.
