Numbers used for packages

Each package lists the relevant SBMLTypeCode_t in an enumeration. This 
list shows the value of the first entry for each package.

Also each package uses an error id offset to internally maintain different
numbers for different errors. These are shown here.

Note these numbers are only ever used internally in libSBML.
