Feature: Paper log form generation

Completed the implementation of a facility for generating and printing paper log forms for people who wish to log offline and then transcribe the data to the application later. A new ``Print paper log forms'' item on the Utilities menu displays a form which allows the user to select the first and last month and year (the form is preset to the default of all months in the current year). The current, previous, and next years may be selected. (If the user sets the end date before the start date, they are silently swapped.) When the ``Generate'' button is pressed, a new window opens with the log document in it, and after a one second delay to allow the page to render, a print command is queued (these features require JavaScript to function; if it is absent, the log document opens in the same window as the request form and the user must print it manually and return to the application with the ``Back'' button). A paged media style sheet is used to insert page breaks so that each monthly log prints on its own page.
