Word Emitter fixes

The DOCX emitter now generates Word 2016 format. This prevents rendering errors with newer Word versions for tables with indented text in the first column.
Furthermore, a bug in the Word emitters (DOCX and WPML) was fixed: Bug 519375: Birt inserts an extra space in DOCX if part of the word is highlighted using an HTML tag.

Edit 2020-08-10: I generated and uploaded the birt-runtime-4.11.0-*.zip once again today, because the file birt-runtime-4.11.0-20200804.zip was incomplete. Several classes in org.eclipse.birt.report.data.oda.jdbc were missing. This caused exceptions as soon as the report used a JDBC datasource. Today's file birt-runtime-4.11.0-20200810.zip was generated from exactly the same sources.
