Fixed #1. Significantly improved quality of generated thumbnails. Now

they are even better and smoother, than those generated by Steam itself.

Fixed a bug where screenshots with identical creation timestamps were

not copied. Now, if the timestamp overlaps for several screenshots, each
of them has identical basename, but different incremental integer after
the underscore and before ".jpg" extension.
Button padding are now set in-code for a more convenient binary building
across different platforms platform.
Some comments to the code added.

Fixed bug when thumbnails were shown incorrectly in the Steam Cloud.

Minor UI improvement.

Game ID combo box is now editable. Minor UI improvement.

Initial commit.
