BUG: allow Timestamp comparisons on the left

Now tested with Series and DataFrame
TST: add scalar comparison test for numpy object with ndim == 0
BUG: convert 0d datetime64 arrays to Timestamp

You must convert to timestamp on the lhs comparison (or reverse the comparison)
for numpy <= 1.6
BUG: Timestamp compares to nat were inconsistent

For example

    Timestamp('now') > pd.NaT

should return the same result as

    pd.NaT < Timestamp('now')

but before this commit it didn't because when Timestamp was on the left, the
values were compared whereas if NaT is on the left then the truth values are
hard-coded based on rules like NaN.
CLN: minimal change
