Nerf/rebalance siege towers.

- Armor changed from 2h/20p/10c to 5h/20p/2c
- Attack changed from 25p to 10p/5c
- Bonus added: 2x vs structures
- Ranged reduced from 65 to 55
- Elevation bonus of 10 added
- PreferredClasses is now 'Structure'
- Ungarrisoned arrow count decreased to 0 from 2
- Build time increased to 60 from 50
- BuffHeal is now 0 (decreased from 1)
- Health reduced from 800 to 500
- Walking speed reduced to 5 from 6

The idea is for siege towers to be useful for siege, but also for cleaning out large numbers of units. Previously they were very good at the latter and useless for the former. They should still be very powerful units, but not uncounterable and massing siege towers (previously unbeatable if enough were acquired) should no longer be feasible.

Prohibit the user from picking the 'system' lobby name, as that's reserved for special messages.

Adds zlib, curl, iconv and libxml2 to OS X libs build script, to avoid using the non-backward-compatible versions provided by Apple.
Adds patch for zlib configure to pick up CFLAGS/LDFLAGS, to better support SDK builds.

Fixes OS X STL incompatibilities when building against later SDKs and targeting 10.5 (fixes stringstream build errors in these conditions)

A bunch of OS X SDK-related fixes.
Adds runtime support for 10.5 APIs: display modes, bundle paths, system paths, pasteboards. Previously this was compile-time support only, which prevented building on later SDKs while targeting earlier APIs.
Adds hardcoded version for pre-10.6 builds, to avoid messing with deprecated Gestalt or having to add a 10.5 non-dispatch singleton (Grand Central Dispatch didn't exist in 10.5)
