New features

- Added const declaration to .lcm specification.
- Removed transmit_only option from LCM URL. All LCM instances are now
considered transmit only until a channel subscription is made.
- Added LCM_DEFAULT_URL environment variable. If the LCM URL is not specified
during instantiation, and LCM_DEFAULT_URL is defined, then that is used as
the LCM URL initialization string.
- Added documentation for LCM type specification language.
- Added close method to Java LCM class.

Deprecations

- enum is now deprecated in the .lcm specification. Current implementations
will be left functional, but enums will no longer be documented or supported
in future releases. At some point in the distant future they may be
completely removed. Use of const instead of enums is now recommended.

Bugfixes

- Java
- fix enum types. This breaks the API for compiled Java enum types. Changed
java enum value field from private to public so that raw numerical value is
accessible.
- C
- lcm_udp bugfix to eliminate a corner-case infinite loop.
- add mutex to allow only one thread in lcm_handle at a time.

May 5, 2008
===========

- Fix minor issue in lcm-gen for parsing oddly formatted files (those missing
token delimiters at EOF)
- Fix Python enum types. This breaks the API for compiled Python enum types.
- fix VERSION bug in ac_python_devel.m4 (affects OS X)
- Remove a DGC hack that skipped over log gaps > 0.25 seconds
- Try to make JAR file only contain class files, by using build directory
- make lcm-spy more robust to receipt of non-lcm autogenerated types
