Cinfile support

Bug Fixes:

• reuse-last-initialized strategy used to select the last initialized run even if it was trashed; now it ignores trashed runs.

Improvements:

• reuse-last-initialized, reuse-last-unsaved, reuse-across-sessions only query for the last run, instead of querying for every run and picking the last one. Should have no practical impact, except it'll be faster if you have a lot of runs.

Features:

• For Vensim models you can now pass in cinFiles as an option while creating a run. e.g.

    var rs = new F.service.Run();
    rs.create({
        model: 'hello_world.jl',
        cinFiles: ['a.cin', 'b.cin']
    });
