I have some code updates to address the UI for the "any" mana keyword. The updates will
1) automatically choose the right color for a single color mana cost e.g. using an "any" source for a

{U} cost will automatically choose blue without prompting.
2) if a cost has 2 or more color, the choices shown to the user are only the required colors.
3) checks for Sunburst so all colors are given as choice
4) choose a color for colorless cost without prompting
5) checks for ManaNeededToAvoidNegativeEffect when choosing a color for colorless mana.
6) chooses the color part of a split cost, e.g. 2/R, without prompting
7) Added more descriptive title to choice menu.
The user will still get prompted for a color with a hybrid mana cost but the choices are only the two colors in the hybrid cost.
The changes also fix the issue with
Shimmering Grotto reported in the Current Known Bugs list thread but may cause the user to get prompted to choose an ability when paying for colorless mana with a source with multiple mana abilities.
I tested all the cases with single cards but I have not done any play testing in more realistic game situations. Should I check in the changes now or wait till after version 1.2.1?
