Minor typo corrections and documenation improvements.

Docs/manual.texi:
  Expanded and corrected information on case-insensitive string comparison. 
  
  Fixed spelling mistake and lanuage usage in query cache information.
  
  Expanded query cache information by noting that the query cache is flushed 
  when table data changes.
