- CommandContext's valueFlag constructor will now ignore the 0th element of args (no idea why that is even there)

Browse Source 
- Limited flags to a-zA-Z
- Passing null to the valueFlag constructor will disable flag parsing altogether
- Adjusted the error message
- Added javadoc to CommandContext(String[], Set<Character>)
- Added CommandContext(String, Set<Character>)
