Update chmlib to 0.35.

Changes:
    - UTF-8 filenames, while still not handled correctly, are handled a little
      more gracefully.  That is to say, the library doesn't fail to open files
      with filenames using characters outside the ASCII subset.  I'm very
      interested in any information as to the "right" way to handle \ 
filenames
      of this sort.
    - Files not containing a compressed section are handled properly, such as
      .chw files.  These files seem to contain information about compression,
      but the information is invalid or empty.  The library deals gracefully
      with this now.
    - Files compressed with different options were not being decompressed
      properly.  In particular, if the "reset interval" for the compressed
      section was other than 2 block sizes, it could fail to read some of the
      files.
    - The caching system was improved slightly, in conjunction with this
      previous bugfix.
