Add effort hours field

[phoenix303]

Add support for Effort Hours Estimate field.

db changes are here - topcoder-platform/tc-database-scripts#25

and you can run

database time_oltp;
ALTER TABLE client ADD enable_effort_hours SMALLINT;
database tcs_catalog;
insert into project_info_type_lu(project_info_type_id, name, description, create_user, create_date, modify_user, modify_date)
  VALUES(88, 'Effort Hours Estimate', 'Effort Hours Estimate', 'System', CURRENT, 'System', CURRENT);

fyi, this is looking ok in dev. The only issue is that the field shows until you clear the cache. @skyhit This is related to the same caching issue we discussed.

@ajefts yes, this challenge to fix that is still running.

also I think we should think about the cleanup the messy javascripts, like different version of Jquery, do should I proceed to investigate?
