Centralize numerical input spinners max/mins for easier control

[dcwhite]

There can be a global user setting to manage the max/min of every basic int/float spinner on module UIs (one limit for all of them, not individual limits). This can be set to something large, and if the user reaches a limit, they just have to update one setting and can keep working. Much better than rebuilding the whole program. If certain ranges must be limited (probably no 1000000^3 latVols), these can be enforced in code on a case-by-case basis, with a tooltip help on why it's limited.
