The first paragraph was being handled just by ME_StreamOutParaProps,
but subsequent paragraphs would check if the paragraph was starting or
ending a table. So I moved the code to check for tables into
ME_StreamOutParaProps.

This is a regression caused by commit
54b53b60 which change the code to use
if statements instead of a switch, so the break statement should have
been changed to a continue statement.

Some ILockBytes objects will not really write changes until their Flush
method is called. Also, further optimizations to the storage implementation
will involve caching writes, which will have to be flushed at times.
