New Builtin Functions
---------------------
- miva_struct_member_callback( struct var, function, data var )
  This function can be used to dynamically populate structure members as they are accessed

  Parameters:
  - struct - The structure on which to perform the callback function
  - function - The callback function that will be triggered when a member does not exist in the structure (if the callback function is empty, the callback will be disabled)
  - data - The data that will be passed to the callback function

  Return Value:
  - Empty

  Example MivaScript code:
    <MvEVAL EXPR = "{ miva_struct_member_callback( l.struct, 'CustomCallback', l.data ) }">

    <MvFUNCTION NAME = "CustomCallback" PARAMETERS = "struct var, member, data var" STANDARDOUTPUTLEVEL = "">
    </MvFUNCTION>
  
    CustomCallback( struct var, member, data var ):
    Parameters:
      - struct - The structure that had the member accessed
      - member - The member that was accessed
      - data - The data that was passed to miva_struct_member_callback

    Return Value:
      - The value that should be assigned to the structure member.

MySQL Connector Changes
-----------------------
- Added the ability to have write segregation.  By default, the write connection assumes the read connection's host, port, user, password, and database.
  The following are commands that can be issued via MvDBCOMMAND to change the write connection's values.
  - write_host
  - write_port
  - write_user 
  - write_password
  - write_db

Other
-----
- Added the following values to MvCALL FLAG attribute:
  - "force_https" - This flag will only connect to the specified host if done so over HTTPS.
    If the HTTPS protocol is not used, MvCALL will raise an error.

  - "force_verify" - This flag will force certificate chain verification / IP verification
    even when the engine is configured to not to perform chain / hostname verification.

- Added certificate pinning to MvCALL with the following attributes:
  - PIN-ALGORITHM - The algorithm to use to verify the connected server's certificate e.g. sha1, sha256, etc...
  - PIN-DIGESET - The binary value that should be used to compare against the connected server's certificate

- Added s.callservercertificate as a system variable within an MvCALL tag.  This variable will return
  the server's certificate in PEM format.

- An MVBRedis.DLL library is now distributed with the Windows installer which will allow MivaScript code
  using redis functios to compile.  It should be noted that redis is not supported on Windows and this
  library will return "Unsupported" for redis_last_error and 0 for all other redis functions.  It was only
  added so developers could compile code related to redis on Windows, but the binary will need to be run on
  UNIX based systems.

StoreMorph Changes
------------------
- Added <mvt:capture variable="l.data"></mvt:capture>
- Added the pin-algorithm and pin-digest attributes to <mvt:call>
