* Lossless image optimization (using ImageOptim).
This shouldn't change the visual appearance of any images. ImageOptim
was run with the highest compression setting except that JPEG metadata
stripping was disabled because some users prefer to avoid stripping
JPEG metadata.
* Update READMEs that have Changelogs for themes impacted by lossless image optmization change.
* Add entry theme
Theme created by @beafialho
* Bump stylesheet version
* add showcase URL
* Remove "theme" attribute from template
* Compress big image files
Lossless compression had a minimal effect, but it's worth a try.
* Fix typo
* Change initial release version to 1.0.0
