New entrenchment graphics mod

[TonyE]

Icamp, no more sandbagcircles, i haven`t played assault missions in years because of those as i always thought the circles looked...well....somewhat "less" and ruined the visuals.

The reason for the entrenchements not being transparent in the middle is that i imagined them as showing wider positions dug into the ground for larger equipment like artillery and vehicles. The bottom of these positions would thus not have trees or grass visible.

However, choice is good or so they say, so i`ve included another zip with the same icon file but in this the entrenchments are transparent in the middle so that the original terrain show through. This way the players can chose which type to use themself.
