v0.1.0

This version adds the ability to:

• choose a custom date format for input dates passed as arguments
• choose a reporting period different than that used for calculating the accruals

This release also tidies the help message to make it nicer to look at

v0.0.1

This is the first useful release of hledger-accrue.

Although it's missing some things I would like it to do, for now this will likely serve 90% of all use-cases.
