- TracerRenderClass uses texture clamp (like SpriteRenderClass).  This should fix texture weirdness at the edges.  [Ken]

- Fix for bugzilla #626 - shell UI being over-expanded after an alt-tab. [NM]

- Included the mpvehicles.odf that's been in my development assets for a while. Forgot to copy it over for sub-builds. [NM]

- Tug skips collision with its cargo (and vice versa).  [Ken]

- Fix for bugzilla #625 - added an option for a periodic kick to re-attack the offending units. Added to .aip files:

[section "ClearArea" or "DefendArea" or "Defender"]
ResendAttackersTimeout = 60.0 // number of seconds between re-orders to attack, use 0 to disable

   This allows a re-send of attackers on a periodic frequency and can be disabled as desired. This change did break compatibility with savegames with one of those AIP chunks, sorry. [NM]
