Use tooltips that call attention to new features

[cmdalbem]

Sometimes we develop new features that we find that might interest most users but it might not call too much attention on the UI for recurrent users.

We'd like also to have some control to show these tooltips only once, and probably only for users who had accessed CicloMapa already before.
