HASH Autocomplete case sensitivity

[awilliamson]

Currently (0.7.3) the autocomplete suggestions for Item hashing is case sensitive. This means that if I wanted to do

lb r1 HASH("air this would provide no suggestions. This relies on the user knowing what the casing is internally. and feels antithetical to the purpose of such completions.

I would propose that the search be case-insensitive. E.g both lb r1 HASH("air and lb r1 HASH("Air give completion suggestions. When a user selects a suggestion, it should put the correct case sensitive variant in.
