Set up the p4_web_api related projects to be loaded by the parent Gemfile to make it a little easier to launch a test p4d with different seed data.
Also fixed a couple of minor issues related to the client api.
You'll notice that the 'rake api_reset api_init' task sets up a p4d for the p4_web_api tests, where the 'rake proj_reset proj_init' tasks set up p4d for project services testing.
An example p4_web_api.ru that can be used for launching just the p4_web_api:
require 'p4_web_api'
# Do *not* let your development environment variables pollute how the p4 web api runs!
ENV.keys.select { |k| k =~ /^P4/ }.each { |k| ENV.delete(k) }
