Modern MRBS Theme

A modern theme for MRBS based on Bootstrap 5.0.

Features

Recommended: Use my mrbs docker container. This makes sure that you always have a compatible version of mrbs and removes the need of manual installation and upgrades
Alternative: Place the folder modern from this repo into the Themes folder of your mrbs. (eg. /var/www/mrbs/Themes) and add $theme = "modern"; to your config.inc.php. Please make sure, you are using a compatible version

This theme adds some config options which you can use in your config.inc.php:

disable_menu_items_for_non_admins (array): Array of menu items which are not visible to non-admins. Eg:
```
$disable_menu_items_for_non_admins = ["rooms", "user_list"];
```
booking_type_colors (map): Map of Booking type => Color to define colors of booking type without having to edit styling.inc. Eg:
```
$booking_type_colors = array(
  'M' => "#73C78A",
  'K' => "#BEBFC2");
```
enable_pwa (bool): If set to True, the PWA is enabled. False by defualt. Eg:
```
$enable_pwa = True;
```
user_can_edit_profile (bool): If set to True, the user can edit their profile using a button in the navbar. Eg:
```
$user_can_edit_profile = True;
```

There is only one supported MRBS version for the latest version of the theme. Older versions won't receive any bugfixes.

This theme is a quick and dirty workaround. As MRBS does not have a real theme engine, it simply injects JavaScript which then modifies the page after it is loaded.
Some pages may not work in certain scenarios!
