#833 Inform user about status of project loading/saving

[bluehazzard]

Add a progress dialog to inform the user of the status of project loading and saving.
At the moment codeblocks freezes and shows the "working" mouse cursor. Specially for large/many projects where saving can consume some time this is not user friendly.

We do not want to introduce UI code in the sdk part, so we probably have to give some UI-Interface-class pointer to the loading functions and if we run in headless mode this pointer should point to some console output printing?

Info from ticket 825:
As discussed here: https://sourceforge.net/p/codeblocks/tickets/809/
some progress dialog for workspace and project loading would improve the user experience a lot.
The code should be similar as the project manager ui code, by passing an object to some UI.
I think a simple wxprogressdialog, could be the first base for this UI.
Should the UI also contain some Message output at the end (for example that some projects failed to load?)
Any ideas?
