Buildable (#36)

- Buildable missions now working. 
- FARPS and BLUESAM zones are now buildable. 
- Secondary Logistics missions are created as buildables become available. 
- Logistic missions can be "marked" with a MAP marker. 
- Supplies can only be picked up in a SUPPLYHUB zone. 
- SUPPLYHUB zones are active once their parents are active. A supplyhub parent can be oneof: FARP, AIRBASE, STAGE. 
- Required supplies for a zone can be configured in kilos. 
- Crates can be picked up with 1000 or 2000 kilo per crate. 
- Max load for a helicopter is set based on public data. 
- TO COME: Sling load options

+                    Supply hubs are used as zones to pick up logistics for logistic missions. <br/>
+                    They are activated when their parent is activated. <br/>
+                    Activated depends on what it's parent is. <br/>
+                    If it's a stage. It can be SUPPLYHUB_A_[name] when you want it to be active when the stage is initiated. (red state) or SUPPLYHUB_B_ it you want it activated when it's BLUE only. <br/>
+                    If you place the Supply Hub trigger zone inside of a FARP zone the supply hub will activate when the FARP zone is activated. <br/>
+                    If the FARP needs to be built first, then that means the supply hub also is activated later. <br/>
+
+                    NOTE: The supply hub does not spawn anything, but merely give options to pick up logistics.

+                    Buildables are zones or objects that first require logistics. <br/>
+                    Eg. A forward SAM site or FARP requires logistic crates before it can be built. <br/>
+
+                    To make an item buildable add a text box inside of the trigger zone and name it: <span class="inline-lua"><span class="lua-variable">buildable_[freeform]</span></span> <br/>
+                    Then in the text box type amount of kilo's you want to be transfered before the logistisc mission is complete. <br/>
+                    The base will slowly build up with each crate giving both a nice view of it happening AND it's good for performance as there's not a big addition of objects at once. <br/>
+                    Right now a crate takes 15 seconds to unpack per 500kg. Meaning 2 crates of 1000kg will be faster than 1 crate of 2000kg. <br/>

                 <p>
                     Runway bombing can be a very effective OCA tactic. With Spearhead we've tried adding as much logic and detail to it so it will feel as engaging as possible. <br/>
