Add notes field

[cfilipov]

I know I should add a notes field for general free-form text (it's been requested by a few people already). The question is, should notes be allowed on each set, on each workout, or both?

I vote for both.

Use cases for workout-level notes:

• "Didn't get great sleep last night, feeling off"
• "Coached by Wayne today"
• "Did the best I could at this crummy hotel gym."

Use cases for set-level notes:

• "Really focused on keeping my knees out, felt good."
• "Wayne said this was the best-looking set he's seen me do."
• "Easy until rep 4, after that it was a struggle."
