extend "Perform the selected actions on save"

[nimo23]

Would be nice to extend the dialog "Perform the selected actions on save"" with a selection of available eclipse run tasks.

With this, user can automatically execute a eclipse run task (for example, gulp task, npm task, etc) after saving a js/jsx/ts/tsx-file.

Maybe it is worth to provide a standalone plugin for this (for example, "RunOnSave"-PlugIn).

In the past, this was done by eclipse ant-tasks where we could hook into save/edit-actions and perform actions. However, as I see, this is no more supported within actual eclipse ide.
