commands: handle property clamping in m_option
Instead of clamping property values to the valid range in each property
implementation, handle it in the property layer. The functionality to
handle clamping for each type is in m_option.c.
It's not really clear whether this is really needed. Normally, the raw
values for M_PROPERTY_SET come only from m_option_type.parse (setting
properties as string) or from m_option_parse.add (using the "switch"
input command). However, since this was already done before, and since
we _really_ want to be sure only to write valid values, add this code
anyway. The newly added warnings/error messages should never actually
be printed during normal operation and are for debugging (if they
happen, we definitely want to see them).
