Add support for updating multiple projects in a workspace

[gayanper]

When working with multimodule project or multiple projects in a single workspace, It would be really handy to have a global Update project command to update all projects in the workspace.

One quick suggestion is to add a command in the project view after Clean Workspace.

Could you give more description about: update all projects? What should be the expected result after triggering that?

When i trigger this new command i would expect the current update command to run on all projects. Today the update command update maven dependecies and update the classpath configuration.

I see. Thanks for the explanation.
