Update dependencies [WIP]

[gaelforget]

1. with these updates the tests suite all seem to work except for one aspect

• the resetting of longitude to -180 + 180 no longer works on the fly
• I edited lon by hand in the sresa1b_ncar_ccsm3-example.nc file as a quick workaround

2. not sure how much this helps but I figured you may want to know

Thanks for your PR :) Seems that YAXArrays 0.6 but not 0.5 raises ERROR: LoadError: lon must be within [-180, 180]. This is because YAXArrays now uses type lon instead of Dim{:lon}.
