Increased EU character analysis range
Performance improvement -- stop processing filters if the character count is already 0.
Removed commented code
Fixed segfault in debug mode caused by previous commit
Skipping OCR processing when num of possible characters is too small
Added a height filter to character analysis -- helps remove noise so that a good plate doesn't get rejected
Updated debug text to be more specific
Added parameter for max plate rotation (was previously hardcoded at 10 degrees).  Upped the default to 15
