Allow viewers to choose how much they pay-to-play, with a minimum value

[criticaltv]

Currently, users of the apps published using the pay-to-play android template must pay a fixed amount per unit-of-time (e.g. per minute).

This issue proposes to provide a way for users to choose how much they pay per unit-of-time, with a fixed lower limit - i.e. they cannot watch for free, but they can:

• increase how much they pay to be above some "suggested" amount

• decrease how much they pay to be less than the "suggested" amount, but above a fixed "minimum" amount.

This would require:

• Design - mainly UX/UI, but also design how this will work tecnically
• Usability Testing - does the feature work with real people?
• Development - actual writing the software.
