CP-397 Add excludeFromAll feature

[maxwellpeterson-wf]

Problem

It is cumbersome to prevent some task from running. Currently you would have to figure out which tasks depend on it, and explicitly exclude it from each, like so:

Trying to remove the libraryDist task

taskTree: {
    dist: {
        exclude: ['libraryDist']
    },
    "minify:css": {
        exclude: ['libraryDist']
    },
    "minify:js": {
        exclude: ['libraryDist']
    },
}

Solution

Support a special-case taskTree option to exclude a task from all. Reduces the above case to this:

taskTree: {
    excludeFromAll: ['libraryDist']
}

Note that includes take precedence. So this will still work:

taskTree: {
    excludeFromAll: ['libraryDist'],
    fullDist: {
        include: ['libraryDist']
    }
}

Fixes #113
