Proportions mod 1.5.3 released

[PvK]

See http://www.latibulum.com/pvk/proportions/ for the new files.

This Version is mainly a set of adjustments and corrections to 1.5.2. I'm hoping to post a 1.6 tomorrow which will involve greater changes. This Version is designed to fix things while changing as little game balance as makes sense, for players that want fixes without having equipment abilities change during an existing game.

Changes in Version 1.5.3:

* Corrected size of Advanced Armor II.
* Corrected tech level requirement of Singularity Generator V.
* Changed standard armor availability to Ship/Base/Sat, because all-armor
drones were so hard to stop, due to the "all or nothing" drone damage
allocation.
* Added old armor types as "Ablative Armor", for use on drones or other
units (if people want weaker but always "hit first" protection).
* Also added standard and emissive drone armor.
* Added new armor types for satellites and weapon platforms, to better
balance against shield abilities, since units don't track component
damage.
* Changed efficient engine family so that regular engines won't upgrade
to efficiency models, and so both types are shown when "show latest"
is selected.
* Fixed an apparently harmless typo in Combat Sensors VIIa.
* Fixed the spatial rupture typo bug from Gold.
* Changed the previous default system type name to "Abnormal Sidereal"
and added a new "Sidereal" variant as the default type. This type
does not have so many planetless systems, so it is much better for
the current AI to navigate through.
* Reduced the average number of planets per system, introducing
seven new system types and adding them to all quadrant types.
