#108 Add support for .ots files (corrected)

[Anonymous]

Sorry, previous posting had typographical errors. Here is the correct text:

Add support for opening/converting OOo spreadsheet "template" files with .ots extensions.

Failed to open file with .ots extension, but when renamed to .ods it worked fine. OOo template files have a .ots extension.
