Easier way for new users to set Starting 1RM values for all Exercises

[Bruno-366]

I suggest prompting a new user to input body weight and experience level.
Then based on that input adjust the starting weights for all exercises, rather than a user having to go through the entire list of exercises (which can be quite varied in some programs) and update the values one-by-one.

For example Strength Level has the following experience levels:

• Beginner
• Novice
• Intermediate
• Advanced
• Elite

While Symmetric Strength has the following experience levels:

• Untrained
• Novice
• Intermediate
• Proficient
• Advanced
• Exceptional
• Elite
• World class
