Fix workfow parameter connections and default values

in workflow editor and run form.

The main problem was that
`default_source = dict(name="default", label="Default Value",
type=parameter_type)`, where `parameter_type` is the top-level
parameter that is always `text`. This has changed with the
Conditional introduced in 20.01.

In addition BooleanToolParameters use `check` instead of `value`.
I also added ColorToolParameter.

One thing for dev is that I think we should pull the default
values out of the optional conditional so we can set defaults
for required parameters.
