Fixes #5, Added "inverse whitelist" feature

[shumatech]

This commit adds a feature to turn the application list into a blacklist where only matching applications have the device blacklist applied. The use of the word "blacklist" was specifically avoided in order to not be confused with the device blacklist. This feature includes the following changes:

• HidHide driver - added two new ioctl's that set and get the inverse whitelist flag. Changed whitelisted logic to apply the inverse state.
• HidClient - added "Inverse application cloak" checkbox to change the inverse whitelist state in the driver.
• HidCLI - added inv-on, inv-off, and inv-state commands to control the inverse whitelist state
• FilterDriverProxy - changed to remove the client's path from the whitelist if the inverse whitelist flag is on
