Truncate beer/brand names based on number of glyphs

[ryanavella]

It would be nice to truncate beer/brand names based on number of glyphs, as opposed to the number of bytes or runes.

I can't find any decent libraries that can calculate the visual width of strings. Here is a quick and dirty approach we could try:

1. Normalize the string to NFC
2. Convert string to []rune
3. Calculate the length of this

We need to extend this to the Menu as well, for beer name, brand name, and style name

We have a lot of code duplication with regards to nicknames and truncation, maybe we ought to consider rewriting it all in a more extensible way.
