Don't warp crafts when they travel over the poles
Notify player when disarming grenades in pre-battle
center on alien melee/psi attacks
don't center on dead units

previous commit took care of the case where it was relevent
smooth scrollin' bullet cam

not gonna put this in the options menus, since it's getting overhauled,
and that's just gonna create more work. not gonna add strings for it either
because i'm not sure what the implementation will be.

for the time being, to see this feature in action you will need to add the
following line to your options file:

battleSmoothCamera: true
ok, add translation strings and in-game switching for now

better to have it and not need it than need it and not have it.
missed a capital letter :P
add hotkeys for base selection, fix error in controls menu

guess i neglected to update the array size statics when i added some new keys
all fixed now.
save the last selected base (for this play session)
Confirm fire mode

mostly for touch devices, although it may help prevent misclicks for mouse
users as well.
Merge pull request #792 from DouglasMeyer/craft_pole_teleportation

Don't warp crafts when they travel over the poles
Workaround for buggy mouse movement in fullscreen in SDL with absolute positioning pointing devices (touchscreen, stylus). Creates an invisible hardware cursor. Borrowed from grafx2 (https://code.google.com/p/grafx2/source/detail?r=1553).
Fix bug if dont use Win or GNU compiler

`CPUInfo` was used without declaration. Nobody spot this because no-win compilers are GNU or pretend they are GNU (Clang).
include mod indexing on unit sounds.
