fix for
bug #117: Incorrect description of modifier “divide teams”
make hog fallback (flower-in-hole) positioning respect limits (e.g. used by gfDivideTeams)
Minor changes to the travis file
Reuse TRAVIS_OS_NAME for ios, move the ios checks after all the others,
add a new line between sections, drop unneeded search path for osx.
Added "Forts" to map type selection. This makes the mode easier selectable/discoverable. Also the slider can be used to adjust the distance between forts.
Set install dir for emscripten
While not required, should help compatibility with older cmake versions.
