Packets now dynamically allocates more memory when they need it.
Increased local receive buffer for Client and Server() and removed the magic number that was used
In Server.h and Client.h
(char readBuffer[INPUTSIZE] = { 0 }).
Packets start size has now been increased to 512 bytes.
Changed ComponentInfo::FieldsInOrder to store strings instead of pointers.
Removed HasEntity() and are now using ValidEntity() instead.
