1) Upgrade the pilot file code to correctly save flags whether entries are added *or* removed
2) Make the tech-db/tech-db-multi ship flag handling consistent
3) Add scripting support for intel entries
4) Add scripting support for adding and removing entries from the tech room
5) Minor cleanup
This maintains the type information which can be used for enforce
const-correctness and also for implementing more advanced ways of
handling the type information.
The bounds check was not correct for 1-based indices. I moved the
Lua->C++ index conversion before the bounds check so that it makes
more sense.
Also, atoi isn't a reliable way for converting a string to an integer.
