Title: Handle charsets that are quoted as if they were not (trim them). 

Handle charsets that are quoted as if they were not (trim them). I encountered some sites that have charset="utf-8" instead of charset=utf-8 and can not access their content. All browsers however accept the charset.

Testcases:
1.) parseCharset("\"utf-8\"") == "utf-8"
2.) parseCharset("'utf-8'") == "utf-8"
