Very minor tweak,

Resolves issue with grid owner conflicting with block creator resulting in used space ship salespersons exceeding block limits when they own nothing because they sold them all. This also removes the need to disable players ability to delete their own blocks anymore. Big thanks to zataralee for testing it for us, and to Screaming Angel for the fix.

Workaround - to further reduce incidence of crashes related to LCD updates.

Gets rid of the made in development version error hopefully!
Increases default minimum registered player trade zone size to 20 to make life harder for cheaters.

Workaround: additional catch on font

Workaround: Adds a catch to more elegantly deal with sese etc exceptions relating to updating LCDs.

Ok, hopefully THIS time this fixes the player market reactive pricing issue.

Fixes issue where player owned trade zones were getting reactive pricing.

ModAPI updates. No new functionality.
