Make Iron Curtain work

[MustaphaTR]

Fixes a part of #26.

I tried changing Cursor but didn't work not sure why.
When activated first time last frame of active anim stops there and doesn't get removed.

Do we have charged anims in OpenRA. In RA2 SWs goes to their charged anim when 1 minute left.

I remember Iron Curtain being commented-out for some actor definitions in the past.
Please find out why and be sure we aren't introducing duplicate definitions.

I took a look to code now but couldn't see anything commented out about IC.

@abcdefg30: Could you test this ingame if you have time to verify valid sequences?

[abcdefg30]

Looks good to me. 👍 / ✅

A few sidenotes though:

• The idle animation stops after using the curtain once
• What does ngiron_f do? (I suspect that could be the active animation)

[GraionDilach]

ngiron_f is the charged sequence. https://github.com/Phrohdoh/oramod-ra2/blob/master/extra-files/art.ini#L1369

In RA2, when the SW reaches 1 minute cooldown, the building plays SuperAnimTwo once, then use SuperAnimThree as idle overlay until the SW gets fired when SuperAnimFour is played to go back into SuperAnim.

Is that setup currently possible?
If not the idle anim should at least be fixed then this can be taken.

[GraionDilach]

Best we can do atm is to make a GrantUpgradeSequence from SuperAnimTwo and SuperAnimFour using combined sequences.

@GraionDilach I'm pretty busy currently, would you mind opening a follow-up PR if I merge this as-is?
