Update checker a bit

Added tag 0.9.23-release for changeset 8610462e3d33

alt damage should default to false

remove the annoying ????

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.

- More files to ignore - Remove ancient kdevelop project file
