Add file extension and size to sorting capabilities (#1029)

Browse Source 
* Add ability to sort by extension and file size.

Use the tags [[extension]], [[size]], or [[-size]] in the
g:NERDTreeSortOrder list to accomplish this sorting.

* Prevent metadata tags being misused in getSortOrderIndex().

* Apply metadata tags only to files.

* Update NERDTreeSortOrder in help file.

* Update version number in CHANGELOG.
