Changes flash render quality default.
As there is a minimal visual difference and a noticable performance drop between 'medium' and the default 'high' rendering quality in flash, this extension turns quality of flash embeds to 'medium' or 'low' (as chosen in options) as flash default.
Primarily designed for low end computers that have trouble playing flash, but also useful for people like me who have tens of tabs open with flash eating up all the CPU.
0.10.1.10: added options screen so you can pick desired quality.
0.9.12.27: initial release for fixed 'medium'-quality
