3.6.0

• add promise-based dialog helpers: ldcover.alert, ldcover.confirm, ldcover.prompt and the generic ldcover.dialog, as drop-in replacements for browser native dialogs.
• add minimal structural styles for dialogs ( nested class hooks under .ldcv.builtin ) for host theming.
• dialog visual styles are separated into themes, picked by the theme opt ( or the ldcover.dialog.theme session default ): default ( bundled look ), bootstrap ( injects bootstrap's own classes onto elements ), generic ( unstyled, the default ). custom themes via the ldcover.dialog.themes registry.
• dialog skeleton can be customized by overriding ldcover.dialog.dom.
