crude time profiling wrappers
accordionizer init routine refactored
- canvas initialization now proveded by AccordionizerSlide object method
- async image loading and canvas initialization
- grayscale() method moved to 'filters' property of Accordionizer() object (more filters implementation planned)
- minor options and variable names tweaks
- example page reworked
- synchronous time profilers removed (they are useless with async plugin code execution)
