luci-theme-bootstrap: add explicit dark/light mode selection
Register two further "virtual" themes called BootstrapDark and
BootstrapLight which force dark and light mode respectively.
The actual Bootstrap theme itself will continue to auto-select
dark mode preference based on OS/Browser preference settings.
