Include help file for turbo pascal

The file is compressed with the technique shown here.
exp.c (new file) is written to show turbo.msg messages.
trie is being converted in a module (header and .c files)
to be used in programs.
Modify Makefile to include exp program
Add turboes.msg with spanish messages
Separate trie.c in a module (trie.{h,c}) and main

We have separated trie.c in a header file, module and
main module (trie_main.c)
Add a data field to be used in the reference
Finally it works multipass
