[Qt-creator] Plugin to display compile errors warnings etc. inline

I was hoping to be able to somehow add an Icon to the FIXME, TODOS.

I am fine with that.

I see. So there are multiple Categories like "QML,Compile,Build System".
Those categories all belong to the "Build Issues".

At the moment I created another category "todo" for the FIXME/TODOS/HACK etc.
All comments are added into the "Build Issues" pane as well, just like the compiler
warnings and errors and it would make it easier for the eye to have a "todo"-Icon
for each entry.

I am not quite sure right now if the "Build Issues" really is the correct place for it.
In terms of functionality it is: I can navigate the todos like the warnings/errors
which makes it consistent (and easy to implement ;) )
But on the other hand TODOS and FIXME entries are not really "BuildIssues"...

No, I am using a quite simple minded approach. As I want to have all additional code
in the plugin I do not want to modify QtCreators code if it is not necessary.

I have three triggers that I use to start the parsing:

1.) Whenever a new editor is opened I read its contents and parse each line for comments
    starting with a given keyword like "TODO","FIXME","HACK" etc. to build up an internal
    list of the items and I add them to the taskwindow via the taskhub.

2.) Whenever the current file is changed (saved etc.) I do the same.

3.) Whenever the current text is changed I look on the current line where the TextCursor is
    and just parse that line. If it contains one of the searched comments I check if there
    already is a "Task" for that line. If so, then I just modify that task. If not I add a
    new one.
    If the line does not contain a comment but I already have a task for it, I remove that
    Task.

At the moment I looks like the attached screenshot.

Markus
