fix(RTL): Unfixed .css() call post-jquery

Removing jQuery broke any .css() call that's reading inherited styles.
Updated the normalize/denormalizeScrollLeft calls in gridUtil to use
getStyles().

Fixes #1620
fix(Column Menu): Fix for position in all browsers

The offsetLeft value for the grid was different between Chrome and FF,
causing the column menu position to be wrong.  The reposition() function
now uses getBoundingClientRect().left for the offset value. This appears
to work in FF, Chrome, and IE11.

Fixes #1649
Add throttle to scroll event
fix(core) row searcher was trying to call an api when the api wasn't available yet
Enhancement(rowEdit): allow suppression of timers, fix getRowsDirty

Timers can be suppressed by setting `rowEditWaitInterval` to -1, which
means user must manually call `flushDirtyRows()`.

getRowsDirty and getRowsError now return `[]` if there are no rows,
rather than undefined, allowing users to call `getRowsDirty().length > 0`
without doing a null check.

Fix #1023 (rowSort): allow nulls to propagate to sort functions

Add a new core.api of sortHandleNulls, and use this same method in
each of the sorters.  Add unit tests to sorters.  Minor fixes along with
that to allow false values to be sorted, and to not accidentally fail to
sort 0 and false values.

Extend tutorial to demonstrate sort function.
