[wog] some commander extra stills are broken

[swats-the-floran]

Describe the bug
when you get two master skills you have to get an extra skill as an option at the next level. it doesn't work with 3 extra skills:

1. permanent max damage (attack + damage skills)
2. block physical damage (defense + speed)
3. fire shield (defense + magic power)

if you add one more master skill you can see that broken skill is presented but you can't see its picture and choose it:

researched a little more. thought the problem is in missing icon in vcmi-extras.bonusicons submod but after checking for fire shield ability i found both config and icon.

btw skill "e_spfire" does not have description.

[swats-the-floran]

the problem is also with non-living ability and reduce damage

[swats-the-floran]

can i help somehow? maybe i can check something to save your time?

Can partly confirm it's still an issue in 1.7

1. permanent max damage (attack + damage skills)
2. block physical damage (defense + speed)

These 2 do not have an icon and corresponding text for some reason.

Can reproduce, but not a vcmi bug I guess?

3 missing icons as of right now:

• FEARFUL bonus - probably extras need to update to reuse old icon from FEAR
• ALWAYS_MAXIMUM_DAMAGE - no such icon in extras. So needs icon?
• NONE bonus - looks like not implemented ability for Defense + Speed skills. I guess we could replace it with something else? Any suggestions? Comment says that ability supposed to be "gives chance to completely block one enemy attack per turn"
