Allow billable value to be set globally, by project, and by record

[jenlampton]

I've so far been unable to unable to create any record with a billable state set. Every project created is non-billable by default, and my config gile seems to have no affect on billing for new or existing projects. My file is named config.yaml but I also tried config.yml (since the README includes both).

global default
I would like to be able to set a default value for billable to true. This value will be used for every project that does not have billable specified. Perhaps somehting like
timetrase set global billable yes

project default
Additionally, I'd like to be able to specify a billable default state for each project on creation, something like
timetrace create project abc --billable=yes

record override
And finally, I'd like to be able to specify a value for billable when a record is created, something like
timetrace create record <PROJECT KEY> {<YYYY-MM-DD>|today|yesterday} <HH:MM> <HH:MM> --billable=yes

Here's my current config.yml:

useDecimalHours: "On"
projects:
    blog:
        billable: true
    hqq:
        billable: true
    sfbra:
        billable: true
    vitals:
        billable: true
    datav:
        billable: true

And yes, the useDecimalHours: "On" does appear to be working as expected :)
