Remove 2 unused number tags in Construction Mode GUI
These numbers are shown aside the power tag, but the numbers never change.
They don't serve any purpose and are just visual clutter and annoying, since
they partially overlap.
They are probably a leftover from copying code over from other scripts.
With this changeset, only the power and turn time are left visible, as it is
supposed to.

Reason: We suspect that this patch might break Windows builds and render the mouse on Windows unusable.
This suspicion is based on the bug report of one user: https://hedgewars.org/node/6837#comment-33593
In return, this changeset will definitely re-introduce
bug #512.
