Allow custom queries to easily use table prefix

[Nodren]

similar to how if we write a custom query, we can use ? to represent an argument, could we add something similar to represent a table prefix?

just as a suggestion, i've seen other apps accomplish this by enclosing the table in {} brackets. so if the prefix was kohana_ then the query would be written like:

select * from {table} where field = ?

and would show up like:

select * from kohana_table where field = 1

added a patch for accomplishing this...its in the form of a class extension, but should be self explanitory to impliment into the actual database class
