Miscellaneous improvements

[dpikhulya]

This PR includes the following:

• Adds field color customization properties to InputField and DropdownSelector.
• Adds Money.format() extension, which, unlike the existing Money.formatAmount(), also includes the currency code, which provides a full set of information about the money value that is sufficient to understand its value.
• Ensures that subscriptions made by the Wizard component are cancelled when the "Cancel" button is pressed.
• Simplifies ComponentSetup declarations (no explicit instance creation is required now). The component's type instantiation is inferred from the ComponentSetup's type parameter automatically (using the same mechanism that is used in EntityChooser).
• Removes the dependency of the core module to codegen-runtime to prevent inheriting its transitive dependency on protobuf lib(s). According to the Chord's design, Protobuf dependencies can appear "starting" from chords-proto-values (in those libs that depend on it).

@armiol As discussed with Oleg, to speed up rolling out the release, I'm planning to merge this PR as soon as he accepts it. I'll address your comments in a subsequent PR anyway, so please feel free to submit your review even after I merge the PR.
