Use different colored underlines for warnings / info messages from g-c-a
Submitted by Elad Alfassa
gnome-code-assistance has various levels of messages, including info, warning and error.
For example, the python backend lists PEP8 errors as info, and syntax errors as errors. Other backends might use the warning level too.
Right now, Builder highlights all types of error (afaik, I haven't seen a "warning" type error yet) with a red squiggly underline. It would make sense to use a blue squiggly underline for "info", and orange sqiuggly underline for warnings.
