[Linux] Better linux support

[ilbonte]

Why many functionalities (like setToolTip) are not available on linux? Is because is not possible or just because you didn't have time to add those yet? Is there a limitation with appindicator3?

PS: some apps that i'm using have tooltips, and also tooltips that updates (e.g. a timer)

After digging a bit it seems that is a limit with appindicator3.
There is PR that adds support for tooltips but I do not think it will land any time soon: https://github.com/AyatanaIndicators/libayatana-appindicator/pull/82

In the meantime the library has been migrated to this repo https://github.com/AyatanaIndicators/libayatana-appindicator-glib and the pullrequest referenced in the above commit has been merged!

This means that tooltips are supported by the lib

The main problem is that the new glib version of appindicator is not yet available on the package managers.

Also this issue might have higher priority
