First, do a ray intersection test with the bounding-sphere for all
entities on the map and then check the more detailed selection shape for
the remaining candidates. Do checks that require component lookups after
the ray intersection tests because these are relatively expensive.
The old method for figuring out which entities are below the mouse
cursor was incorrect because it does a 2D check to filter out the first
candidates which can lead to incorrect results with lower camera angles
and high buildings or buildings with a large footprint. Such problems
were avoided with quite a large radius for this 2D test and resulted in
a large number of candiate entities after this first test (200-500).
Also rename PickEntitiesAtPoint to PickEntityAtPoint and make it return
only one (the closest) match.
I've tested performance with the tracelogger by starting a map and then
moving the mouse in circles for one minute. The results were relatively
stable. I've compared the total time percentage of input.js:836, which
spends nearly all of the time in PickEntityAtPoint.
Ardennes Forest - Normal size: Original: 41.46% Patched: 31.6%
Ardennes Forest - Giant size: Original: 40.59% Patched: 51.55%
As we see, it's faster on normal map sizes but slower on giant maps with
a lot of entities.
This approach can be further improved with some kind of spatial
subdivision for the culling (like an octree), which would help the unit
renderer too. This way it should be possible to make it faster (and
still correct) on all map sizes and with a large total numbers of
entities.

Config settings in a section are stored as "sectionname.setting"
internally.
Do not write section headers when writing config files as we would need
to write
settings without a dot first or ignore them. This can be changed once
all settings
belong to a section.

Per the Apple Human Interface Guidelines the confirmation button should
be on the right. We do that for all(?) other dialogs, but not this one.
This was SVN commit r15977.
Parameters now have to be quoted with ".
Supports " in parameters by escaping them with \.
Tag start characters can be included in normal text by escaping them
with \.
Better error handling and a error messages to help with fixing
invalid/malformed strings.
This was SVN commit r15969.
Fix Engine.ReadJSONFile() which did throw a JS exception that was not
caught. Discovered by s0600204.
Expose Engine.ReadJSONFile() to the gui scripts.

This makes the simulation update faster per entity but also makes the
number of entities greater at a given moment. The performance gain is
positive.
This was SVN commit r15956.
