Major overhaul of default.class.php
 - Updated/included better function comments for all functions
 - Uniformed all return variable names
 - Updated strToHex() function to prepend '0' where necessary and provide optional delimiter
 - Updated hextToStr() to utilise pack instead of looping - hopefully faster processing on large strings
 - Updated morse functions: both now utilise the same array mapping
 - Split wordFreqs() into separate functions for use with hex.php and words.php, adding charCounts()
