Improve embed style

[tigattack]

• Increase max length of artist/album/track names from 18 to 32.
  This solves unnecessary truncation of almost any remixed track and/or "medium" length album name and/or multiple artists and/or long artist name. Agree with truncation on long strings, but 18 feels much too short.
• Split artist and album fields to separate lines

Example of embed with 32 character track name and 23 character album name:

Example of same embed with artist and album fields not inline:

Example of embed with [what I think is] unnecessary truncation:

An argument could possibly even be made for allowing even more than 32 characters, especially given the proposed line break between artist and album fields, but I thought I'd go for what seems to be a safe middle ground here.

Feedback appreciated.
