Move to "G+-style" selection.

To select an item, click the checkmark that overlays on rollover.
To navigate, just click anywhere else on the item.

Also move selection from additive by default rather than exclusive.

Further visual refinements to layout of homepage:

* Increase default image size a few settings
* Increase gutter between items
* Remove extraneous padding and whitepsace
* Remove unneeded gigantic heading
* Move build version into statusbar
* Change algorithm for fitting rows -- instead of preferring to clip
  edges of image, instead prefer to adjust height of rows. I find it
  looks more interesting visually when the widths of the images vary
  more.
* Replace folder and file icon with something better looking
* Swap order of + and - buttons in toolbar, they were backward from
  what is typical

add capctime flag to camput

I can recreate the file, set the modification time, but can't forge creation
time, thus cannot recreate the exact same uploaded file twice.
This change targets this problem.

As this is a very rarely used flag, this is enabled only if the CAMLI_DEBUG
environment variable is true - such as the other "gross" options
(statcache, sqlitecache...).
