Description

When running 1.9-rc1 against govdocs1, I found a few files whose mime-types have changed. I'm posting this now so that others can look...some of these are for the better, and some not.
For further investigation:

• embedded pict and wmf are now sometimes identified as pdf (TIKA-1085)
• several .doc files are now identified as application/x-msmetafile and no text is being extracted
• several .doc files are now identified as jpeg or png and no text is being extracted
• several .ppt files which were being identified as various (jpeg, ppt, png, msoffice, word) are now being detected as excel

Probably for the good:

• a handful of files that were identified as text are now identified as pdf (TIKA-1085)
