[Gradle] Rename all tasks to use camelCase

[scottfrederick]

Tasks in the Gradle plugin are named with the form cf-task-name. This makes it difficult to use the task names in Groovy expressions since the - characters are taken as part of an expression (i.e. a "minus" sign) instead of part of a variable name.

It is more typical to use the form cfTaskName in Gradle tasks. Please comment on this issue if you have concerns about this backward-incompatible change.

just a thought -
would it be possible to have something like:
def cfdelete extends cf-delete()
{
// do some stuff
}
