* 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 the load_theme_textdomain function call
* Fix incorrect domain
* Load blockbase translations
* Moved all calls to load_theme_textdomain to be handled by Blockbase (not the children)
* Refactored calls to load_theme_textdomain to not include the default location to simplify the call
* Added load_theme_textdomain call to block canvas
* Removed unrelated videomaker changes
