Progress update.

* Adds some arbitrary support for public dev build. (YMMV) relates to piston and rotors.
* Adds a new sound (for future features)
* Changes defaults of player owned trade zone being ENABLED.
* Increases NPC trade zone default funds (playtesting shows it runs out too fast otherwise)
* Adds a crude /gps command for quick adding or removing gps's
* (Disabled) adds some tech demo missions - disabled until complete - at the moment it might be exploited in its current state.
* Firedrake_13's ENH - Adds a # code to lcd keywords to allow the lcd to display only items past a particular line This allows you to have more items than a single LCD can display, by telling the second (or third) LCD to only display after the #'s item. Example - The following will display on hand stock and prices of component items line 30 and onwards:
[economy]
component stock #30

3.03A Progress Update
Note: This version has reduced support for the legacy build of space engineeds (DX9) - from this point on we will not be testing if the mod works on older versions as progressive MOD API changes will eventually mean it will not work on both.

In addition to moving to the latest .net frame work to match the game version, this Adds abbreviated versions of various commands to support admins who want to make quick changes to npczones or players who forgot or didnt realize they need a reason when paying another player.
For Players:
/pay reason. Is now optional - If you forget one it just fills a generic reason for you.

Moving player zones is already tied to beacons on ships, and creating zones uses targeted beacons so these do not require shortened versions.

For Admins:
Quick add NPC market zone
If you are in a hurry and want to add a new trade zone you can use the addhere option in /npczone. This defaults to a zone size equivalent to the default 0,0,0 zone. ie. 2500 radius sphere (5km diameter) at the current location of the admin in the world. Names are restricted to a maximum of 4 words. The last word in name cannot be a number this is because you can also specify an optional zone size to override the 2500 default (by putting a number in as the last parameter!)

eg. Create a zone where you are standing called "NPC Asteroid Base" with a zone size of "3000":
/npczone addhere NPC Asteroid Base 3000
Create a zone where you are standing called "Rock24Q" using default zone size
/npczone addhere Rock24Q

Quick move NPC market zone
Moving existing NPC zones (eg moving the default 0,0,0 market) was painful, this allows you to move it to your current location instead of specifying the gps point and all the other settings.
This has the current limitation that zone size will be set to 2500 sphere once moved however!
eg. Move the NPC zone "Rock24Q" to where you are standing/floating:
/npczone movehere Rock24Q
Move the NPC zone "Freds Rock" to where you are standing/floating:
/npczone movehere Freds Rock
