Replace command-score

[timc1]

command-score becomes quite sluggish when the matched search term exceeds ~15 characters for a relatively normal (100+) filtered actions list.

Although for the majority of users would likely never have such a long search term against that many actions, we'll still want to ensure that if they did, performance wouldn't be impacted as it is now.

Closes #247, #252.
