Fix for a Couple of Regex Issues and Respecting Disabled Rules for Special Rules

[pjkaufman]

Fixes #306
Fixes #303
Fixes #300

Changes Made:

• Updated the running of special rules to make sure they check if the rule is disabled before trying to run it
• Updated regex for tail of English to Chinese to make sure a dollar sign is listed as something that needs a space after it
• Updated regex for multiline comments to make sure it starts a line in order to be counted as something to escape to prevent single line comments from getting caught in the regex
• Added tests to make sure we hopefully will avoid reintroducing the above problems (checking disabled rules did not have any UTs added)
