Increased the file count to 16 bits when written to the object file.

Browse Source 
Moved the input file table to a separate module and added an AddFile()
function to add files to this table.
Removed the 8 bit limit for the file number in several places (the file
number is still 8 bits in the file position structure).
Added a pseudo instruction .dbg that will be used to add debug info from
high level code to the assembler source.
Added a subkey "file" to the .dbg command that allows to add a file to the
file table that is later written to the object file.
