Revert "assets: Remove stray image"

This reverts commit 85062ddbaec7158b8dc0b7868aed373964665e82.
genetics: Add missing Marilyn Monroe asset
genetics: Add 2 examples

Closes #32.
genetics: Change webcam filenames format

Changes the names of webcam file uploads to:

    [date]-webcam-[ip].jpg

This makes garbage collection easier, as the files will be
alphabetically ordered by date, allowing the oldest images to be
collected using:

    $ ls | head -n<num> | xargs rm -v
assets/genetics.js: Fix setting default assignment

This replaces the !var checks with var === undefined, which allows for
booleans to be set.
Merge branch 'iss32'
genetics: Start with buttons disabled

This disables the Start and Stop buttons until the page is loaded
