Add mode=replace to [modify_unit]

Browse source 
When specified, replace rather than merge the [unit] sub-tags. Does not effect [object], [trait], [effect] or [advancement].

For example:
    [modify_unit]
        [filter]
            id=Deoran
        [/filter]
        mode=replace

        [filter_recall]
            [not]
                id="Sir Gerrick"
            [/not]
        [/filter_recall]
    [/modify_unit]

will replace the current contents of [filter_recall] with the given contents. Without mode=replace, the contents would be appended to the previous contents.
