Make custom parameters more intuitive, few fixes

[Fort-TM]

This PR tries to partially address #102, since I also got confused about them before. The changes are mostly visual and don't affect functionality

• Make custom rules checkbox text generic, since they affect all game modes as far as I know.
• Disable all custom parameters if the custom rules checkbox isn't enabled. This should make it clear that you need to enable this setting to use them.
• Include tag count when there's any tag selected and sort them alphabetically
  
• Add tooltips for the tag inclusive and skip seen maps checkboxes

This PR also fixes the following issues:

• Minimum value for the year slider was 2020 for MP4 too
• Date interval table used the same name as the tags table. This would shrink the tags table when the date interval one was rendered
• Date intervals values weren't being reset when resetting parameters to default

This was included in a single PR because the changes are small and related to the custom parameters tab
