-removed the new 3rd variable from mist.utils.getDir and just made the
2nd variable optional instead
-Added check to DB update functions to only update if data from the
group has changed from what is currently in the
DB. This fixes an issue I had where some data was lost if you spawned a
group normally after mission start and then
used a respawn, clone, or teleport function on said group
-fixed issue with dynAdd functions naming a group with the country ID
insead of country name
-added mist.getAvgPoint(). Function is similar to mist.getAvgPos except
it uses raw vec2/3 coordinates instead of
units
-added mist.utils.roundTbl() Has the same input values as
mist.utils.round except it accepts a table and it rounds all
numbers in the first level of the table to the passed percision.
-added optional variable to mist.utils.getDir() If present this function
will return the "raw" heading, this is useful in assigning the heading
variable within a task.
-mist.utils.makeVec3 now supports being given a table in WP format.
Specifically it now coverts a table {x, y, alt) to vec3
