Fix for major import issue, Improvements on addRule and removeRule parameters

For addRule and removeRule, quotation mark escape is now done automatically. The following are examples of valid inputs:

gnip.addRule(tag="tag2", value='("TESTFILTER1" OR "TESTFILTER")')
gnip.addRule(tag="tag3", value="(\"TESTFILTER2\" OR \"TESTFILTER3\")")
