Remove $.isNumeric() for compat with jQuery < 1.7. Fixes #1026
Override colors array after extend in parseOptions

(Realted to flot issue #1031: https://github.com/flot/flot/issues/1031)

Currently, if the user declares a custom color palette with less than 5 colors (say, n), $.extend(true, options, opts) only modifies the first n colors of the default palette and leaves the last 5-n in place. When the number of series is >n, colors are used that are not part of user-defined palette, contrary to description of colors array in API.

This line overrides the extended colors array and replaces it with exactly the user-defined colors array, when present. Afterwards, the user color palette is respected by the auto tinting/shading system for when there are more series than colors.
