Support a maximum building range (Fixes #2156).

Browse Source 
This also implements support for a per-provider
cooldown between placing structures, allowing mods
with multiple structure queues to rate-limit
placement around a single provider.

An initial delay parameter is included to
support units that deploy into a base provider and
require an initial setup time (e.g. the Surveyor
unit from C&C TW).

The range and time restrictions are not applied to
walls as a balance choice.
