Title: Add support for merging cells and autofilter parameter 

1) Added a new function merge(), example:
[% merge('A1:A2', "Merged content", "format" %]

2) Add support for an "autofilter" parameter in the JSON template which adds a filter dropdown to every column the given row (typically the specified row will be the headers).
