[Freeciv-Dev] indefinite improvements

[Jeff Mallatt <jjm@xxxxxxxxxxxx>]

The next step towards generalized improvements is allowing an indefinite
number of improvements.  The attached patch does this (though, it includes
a check in the ruleset loader to make sure rulesets still only define the
proper number of improvements to match the still burned-in
improvement_type_id enum).

Includes changes for all clients, though MUI is just an untested guess.
