UploadFields

This is a fork of HydraWiki's UploadFields extension with improvements I personally needed when running this extension on vanilla MediaWiki 1.34.

Changes

• Serbian localization (only the description message).
• New configuration variables:
  • $wgUploadFieldsParameterNamePadding: A number, by default set to zero, that determines the amount of spaces your parameter names will have after their name.
  • $wgUploadFieldsRemoveBlank: Whether blank fields should be removed from template's parameters. Set to true by default.
  • $wgUploadFieldsSummaryParameter: Name of the parameter in which the summary field's text will be inserted.
  • $wgUploadFieldsTemplate: Name of the wiki's file description template.
• Additional spaces are added before and after parameter names, as well as after the = sign, regardless of the parameter name padding settings.
• Removed the previous README as it just copied the MediaWiki.org documentation page.
• Allowed different field labels from parameter names by changing the contents of MediaWiki:UploadFields-label-Name pages. When these pages don't exist, messages remain the same.
• Trimming select/multiselect types/labels.
