Lockheed1049h version 2.10: Introduce refuelling errors

On the real aircraft, tanks were refuelled individually and measured using a
combination of internal and external dipsticks, so loading exact quantities and
having an exact balance between tanks is not realistic.

This commit introduces a configurable error percentage when refuelling, which
provides more realistic refuelling tolerances. It also leads to more realistic
fuel management during a flight because opposite tanks need to be managed into a
state of balance.

Updated Nordstern: Made the mast truck MP enabled.

Updated Nordstern: Added an ALS shadow-vol effect projected shadow and some pending updates.

Lockheed1049h version 2.9.3: repait copilot again

* Nasal/L1049h-dual-control.nas: add the Aircraft/Lockheed1049h/ prefix to the
variables used to identify potential pilots and copilots.

Updated ZF balloon: Fixed the forgotten default renderer balloon envelope shader too.

Lockheed1049h version 2.9.2: repair copilot
Bug similar to the one fixed in 2.9.1; the Nasal file for the copilot must not be
loaded in an XML node named Lockheed1049h.

Updated ZF balloon: Fixed a problem with the envelope wrinkles in the balloon envelope shader.

Updated ZLT-NT: Improved the shadow object and fixed the shadow altitude offset problem.

Fix for dead links in the marchetti aircraft.dat file.

The link to Assoc. Prof. Michael Selig's website for the UIUC aircraft has shifted to
http://m-selig.ae.illinois.edu/apasim/Aircraft-uiuc.html . Therefore the old dead link has been
replaced with this correct link.

Citation II: (v3.0.4)
* typo fixed in cdu
* bump up version number
