Hide apps grid until icons finish loading

Prevent a visual flash by hiding the apps grid until all app icons have loaded. Adds revealWhenLoaded($container) which removes the myapps-grid-loading class when images finish (or error). TabApps now caches the .myapps-container lookup and calls revealWhenLoaded after initial render, after search results, and after loading installed apps. CSS changes: add .myapps-grid-loading (opacity:0 + transition) and a small padding-right tweak for the search input.
