Blocks Coin-Miners from Websites before and after they load.
v1.0.3: Fixed bug in Firefox and Chrome which causes webRequest.onBeforeRequest to NOT cancel the download of bad files. To fix it, I made scanning synchronous instead of asynchronous (a bit slower, but not noticeable). Fixes issue: https://github.com/Brandon-T/Coin-Blocker/issues/1
v1.0.4: Fixed bug in the code which caused some white-listed sites to be scanned and blocked still. Added debugging code to print to the developer's console exactly what was blocked and what was allowed.
