On trunk, visitor log doesn't show all the logs for month #1873

On trunk on my box, Visitor log shows daily data for Dec 5th or other days. Yearly and weekly Visitor log also shows data correctly. However, Monthly Visitor log only shows the log for the Dec 1st.

Also, Yearly Visitor Log shows a "Next" at the bottom of the visitor log, but when clicking on Next no data is shown (only the "Previous" link).

There is a regression in the Log.

(In [3417]) refs #1873 - for consistency with other API functions, remove filter_offset from method signature, and use offset (similar to filter_limit vs limit)

(In [3419]) refs #1873 - calling the API directly should have the same effect as disable_generic_filters=1

(In [3479]) Fixes #1832, Fixes #1873
