Create more granular view permission for user's hour costs

[#1]

Currently I need to have my PM have access to edit financial information. This means that they end up being able to see what an hour costs. While a user's specific hourly rate can be hidden, the cost information cannot be. This means for an hours report, it is very easy to determine what someone's hourly rate is, in turn, it makes it very easy for someone to determine how much someone makes.
