Grey Out Cameos based on TechLevel=

[ayylmaoRotE]

This request is to implement an option, possibly under [TechnoType] that allows the user to see all tech and units that are available, although blocked by technology/prerequisite walls. This would show the cameo greyed out.
e.g.

[APOC]
TechLevel=8
AlwaysDisplayAvailability=yes

The Apocalypse Tank would show in the sidebar as greyed out, until a Battle Lab is built, but since Battle Labs are TechLevel=6, if the map does not allow tech levels above 6, it would still remain greyed out.

Similar to how tech locks work in C&C3

[NukeSpecial]
AlwaysDisplayAvailability=yes

Because the Nuke Missile Superweapon it tied to [NAMISL] which is TechLevel=10, the nuclear missile would be greyed out all the way through to TechLevel 10, until a Nuke Silo is built.
