dwp@mso.anu.edu.au:
New functions unit_type_exists(), tech_exists(), and improvement_exists().
They do bounds checking, and then check whether the specified element has
been marked as "removed", eg in the data tables or by set_civ_style().
Replaced some existing bounds-check code by calls to these functions.
