Code added for calculating federal income tax source deductions. Added categories, rules, input types, etc. for matching up to line 108 in hr_salary_rule_data.xml (TC inputs and rule param). Still missing a bunch of inputs, categories and rule params, along with all the EI calcs and provincial stuff.
