Created Timeline CGI script.

While I can attempt to loop ajax calls to retrieve a bunch of accounts
and lineitems, it really makes it frustrating (in some regards) to have
such convoluted javascript code.

So rather than that, it's much simpler to generate the data I need all
at once and use that. So timeline.c does that pretty easily.
Refactored Timeline.js to use timeline.cgi

It's still doing a month at a time view. I'd really like to do a day by
day view, and I could easily do it for mon-sun, but I'd like to be able
to do it with each day of each month _that are used_ and any inbetween.
Haven't quite figured out the best way to do this yet unfortunately.
Compiled Harp.
Added in day counts graph.

I am thinking I should create a third graph, which will be a bit more
dynamic, I could have a dropdown to choose a month, and then that month
would switch the graph data out for information from that month. It'd be
easy to show a line graph of the spending habits then.
