srowen 15f34edb52 Simple check in Code 39 reader to determine wide bars vary in width a lot, to cut out most false positives

srowen 180e833b3e Improved approach to 1D decoding -- better use of integer math by scaling pattern ratios up to expected number of pixels, rather than the other way. Modified constants accordingly. Also introduced notion of maxium variance that any one bar in a pattern can have and stiill be accepted. Finally, adjusted false-positives test failure limit downward due to recent improvements.

dswitkin f431cae59f - Added support for rotation in our blackbox test framework, and refactored the ways tests are created and run. 
- Turned on 0 and 180 degree rotation for all 1D formats.
- Turned on 0, 90, 180, and 270 degree rotation for QR.
- Changed the 1D code to re-enable upside down scanning, with a dramatic improvement in barcodes found and fewer false positives.

srowen 8d31073968 Detector is now a little more skeptical once it has found 3 confirmed finder patterns -- one may be a false positive, so it also checks to see if the estimated module sizes are "pretty similar". If not, keeps looking.

dswitkin a816d5d9b1 Changed the parsing logic to refer to EAN-8 and EAN-13 as UPCs as well, so that the clients can recognize them as product barcodes and offer to do a product search.

dswitkin ae54d7a937 Changed how many rows we scan while detecting QR finder patterns. The mobile case dynamically calculates this based on the height of the image, and ranges from a small speedup to a big difference for large inputs. Also changed the try harder case to scan every 3rd line for a 3x speedup. The unit tests have the same success rate as before: 16/20 on qr1, 10/10 on qr2.

srowen d1d7e96238 At last, removing SKIP_N_BARCODES and separating this logic out in a way that individual projects can implement it on their own. It's a bit too onerous and project-specific to live on in the main code.
