make action format

We have a lot of 'if the PCs do X, then Y'. Too much of it on one page feels tiresome.

Sentence Structure

I think declarative language will work better:

Climb the walls with Speed + Athletics at TN 10. Failure means falling 4 steps.

(I think we can leave the tie implied here, as it clearly means 'you don't climb', and 'you don't receive the Damage')

Squeeze through the tunnel with Dexterity + Caving at TN 10 plus the character's Strength. On a tie, the character must remove armour, or scrape skin and lose 1 HP.

TeX Structure

\action{#1}% Action
    {#2}% Attribute
    {#3}% Skill
    {#4}% TN
    {#5}% Tie notes
    {#6}% Failure notes

Maybe the action notes could be removed from books with the intro flag set to false, since they're less valuable for people who know the system.

Change Plan

Let's not change everything. I just want to make a new command, and if it feels better, we can replace old sentences while editing or writing new modules.
