* Implemented 'isOctal' to go with 'isDecimal' and 'isHex'
* Implemented 'getHex', 'getDecimal', and 'getOctal' functions which are slightly more efficient than calling 'getBase' with a constant base input.
* Improved how netmask_table is implemented.
Removed some unused, dead, and inefficient code/functions.
General cleanup and improvements, so my eyes don't bleed as much when looking at functions I implemented several years ago.
