Allow numeric tickSize for time axes

[GoogleCodeExporter]

Version: 0.7 (current version)

When setting tickSize in microseconds in the options array and when the mode 
for the given axis is set, to "time", just *must* supply an array, even if a 
custom format is specifed. See example code below. A diff that patches the 
issue is included.

I may be misunderstanding your description of the problem, but yes, tickSize 
and minTickSize currently require an array when using time data.

Since I can understand how you'd want to specify in milliseconds, I'll accept 
this as an enhancement, but, unless I'm missing something, this isn't a bug.
