Drupal: Module Changes and Filter Creation (Project for Drupaler if possible)

Please only bid on this project if you are very experienced with Drupal. No cheat html solutions will be accepted, all must be integrated well. I need a few minor changes here and there on my drupal site: - I'm currently using the Simple Karma module. There is a tiny css bug in internet explorer that needs to be fixed. New version of the module maybe fixes that already, in that case the custom changes to the module simply need to be ported to the new version. - Also for Simple Karma: Change colors of posts based on user role (minor css addition) - Custom filter module: This module allows to make custom input filters. I need a filter that searches for [login to view URL] links and that replaces them with a certain html/js snippet. I have all the code snippets you need and the module is installed (have the regex too) you just need to write 1-2 simple PHP/Js functions for this to work - Also for the custom filter module: Need a custom input filter that parses for [spoiler][/spoiler] text and replaces the text with a collapsible table.
