Objective Descriptors use [ ] to encase some item names

[dev-brendanprice]

Modify the string variable function to replace these with their respective icon svg icons as the information they hold is (most of the time) already present in the objective

[dev-brendanprice]

Edit: This would be present in a different context as the string variable splicer function is only used for string variables that are found in the description of the bounty, as opposed to the singular objective description that is shown above to contain the named variable, encased in square brackets.
