Added query override and ability for filter OR's

[aphex]

Sorry for the updates but please review this i had added the ability to do multiple properties in a filter for something like WHERE x=="10" || y=="10" like this

filters: [
    {
        property: ["Common", 'SciName'],
        value: searchString,
        caseSensitive: false,
        exactMatch: false
    }
]

Also added the ability for store.load to pass in a totally custom query skipping the abstraction

store.load({query: sql});
