Add an indicator for work in progress

[lesquoyb]

Is your request related to a problem? Please describe.
Since the removal of the bottom bar containing the memory indicator, there's nowhere to check if gama is doing some work or not, and it can be pretty disturbing.
For example I have a model where I allocate 100 000 agents, and when I close the experiment it takes more than a minute to go clean everything and go back to the editor but as there's no feedback I thought gama just crashed and was hanging forever.
I think it's the right occasion to have something a bit more visible than before as I noticed that many people wouldn't notice the previous indicator either and would often just think it's broken.

Describe the improvement you'd like
Add somewhere in the GUI an indicator that something is happening (closing simulation, compiling etc.) as it was the case before.

Describe alternatives you've considered
Go back to the previous GUI, but I honestly think that the new icon and location to clean the heap fit way better in the gama interface so I'd prefer if we find another way

Probably could be a good idea to list which activities should be listed there. Because some are already (reading a file, etc.), and others were not even in the previous UI as far as I know (like cleaning the simulations).

I propose the following mockup.

It implies retrograding the "GAML Reference" search down to the editors' level (which makes sense), replacing it with an activity bar (with possibly a drop-down menu when there are many activities), where progress and other status can be displayed, and making the current status bar a space completely dedicated to experiments and simulations (no status except the time, etc.).

The activities that can be listed and tracked here are :

• Workspace refreshes
• Models compilation
• File loading
• Agents creation
• Display updates
• Opening / closing of simulations
• Running of tests
• user messages (with the statement status)
• other ?

works for me, I can't see other operations currently
