(bug 42654) Implement Show changes in Save dialog. Turned saveDialog-body into slide-based swapper. Moved footer into saveDiaog-body so that the license text doesn't stay under the diff-slide (and move body bottom padding to foot top) Wrapped buttons and title in a saveDialog-header and converted closeButton from absolutely positioned to a floated layout. This way the title doesn't need to be repositioned but will scooch over if the prevButton gets shown/hidden. Update API "diff" action to include table wrapper and table header. Without it the mediawiki CSS for diff doesn't work properly (needs colgroups for proper width of the "-" and "+" column etc) Renamed -saving class to -disabled for consistency. Set prop.disabled to really lock/unlock buttons, not just visual (otherwise the click handlers are still triggered on click, can potentially cause actions to be triggered when not expected) Using a ve message for "Show your changes" title instead of re-using core tooltip-savepage in a different context. Diff slide triggers "auto width" on dialog (inline undo of width: 29em), keeping min-width, to allow it to expand as wide as needed. Functions that I copied as base for onShowChanges and onShowChangeError had some incorrect argument descriptions. Fixed in both. Note: * Pass function to .off(), so that only that one is unbound instead of any "resize" handler on the page (by other extensions or gadgets or core) * NB: ve.bind ($.proxy) preserves internal guid, so that $.Event can find the bound function by the original reference. * keydown has an anonymous function, should either moved to prototype or namespaced, did latter for now, save enough and better than destructive .off('keydown') Change-Id: I9d05ef6e3e2461bdcf363232f7b0fbad5e24f506
