Upgrade to Tika 1.9

Release 1.9 - 6/6/2015

  * The ability to use the cTAKES clinical text
    knowledge extraction system for biomedical data is 
    now included as a Tika parser (TIKA-1645, TIKA-1642).

  * Tika-server allows a user to specify the Tika config
    from the command line (TIKA-1652, TIKA-1426).

  * Matlab file detection has been improved (TIKA-1634).

  * The EXIFTool was added as an External parser
    (TIKA-1639).

  * If FFMPEG is installed and on the PATH, it is a 
    usable Parser in Tika now (TIKA-1510).

  * Fixes have been applied to the ExternalParser to make
    it functional (TIKA-1638).

  * Tika service loading can now be more verbose with the 
    org.apache.tika.service.error.warn system property (TIKA-1636).

  * Tika Server now allows for metadata extraction from remote
    URLs and in addition it outputs the detected language as a
    metadata field (TIKA-1625).

  * OUTPUT_FILE_TOKEN not being replaced in ExternalParser 
    contributed by Pascal Essiembre (TIKA-1620).

  * Tika REST server now supports language identification
    (TIKA-1622).

  * All of the example code from the Tika in Action book has 
    been donated to Tika and added to tika-examples (TIKA-1562).

  * Tika server now logs errors determining ContentDisposition
    (TIKA-1621).

  * An algorithm for using Byte Histogram frequencies to construct
    a Neural Network and to perform MIME detection was added
    (TIKA-1582).

  * A Bayesian algorithm for MIME detection by probabilistic
    means was added (TIKA-1517).

  * Tika now incorporates the Apache Spatial Information
    System capability of parsing Geographic ISO 19139 
    files (TIKA-443). It can also detect those files as
    well.

  * Update the MimeTypes code to support inheritance
    (TIKA-1535).

  * Provide ability to parse and identify Global Change 
    Master Directory Interchange Format (GCMD DIF) 
    scientific data files (TIKA-1532).

  * Improvements to detect CBOR files by extension (TIKA-1610).

  * Change xerial.org's sqlite-jdbc jar to "provided" (TIKA-1511).
    Users will now need to add sqlite-jdbc to their classpath for
    the Sqlite3Parser to work.

  * ExternalParser.check now catches (suppresses) SecurityException
    and returns false, so it's OK to run Tika with a security policy
    that does not allow execution of external processes (TIKA-1628).
