[likeadeckofcards]

This PR adjusts the functionality of where method to make the method handle the boolean values set by whereNot method in Laravel's default builder classes.

Fixes #49

override Eloquent/Builder.php applyScopes()

• loop through each find and apply the scope to include requests
• (skip over omits)
• if we find no include finds, we should apply the scope

in where handler for FMBaseBuilder

• if the new find is a where
• add the find criteria to the last include or make a new include before the omits
• if the new find is an whereNot(omit), add a new omit request,
