Scanbot Version 1.0.0.5
* [Fixed] Issue #3 - does not rely on file extension for file types
* [Fixed] Issue #2 - filename properly formatted for recvScan to work
* [Fixed] Issue #1 - detection optimized by use of multiple resolutions
* Checks for file locks
* Handles TIF files
* Brings scan in at a higher (default) res than earlier, hopefully this will
translate to clearer scan display
