LCM 0.8.0 released

[Albert Huang]

Hi all,

LCM 0.8.0 is now released.

This release changes the C++ API, adds some features to lcm-logplayer-gui, and
fixes a few bugs.

lcm-c:
- add new macros LCM_MAJOR_VERSION, LCM_MINOR_VERSION, LCM_MICRO_VERSION to
check LCM version from C/C++.
lcm-c++:
- rename LCM::fileno() to LCM::getFileno()
fileno is implemented as a macro on some platforms, and is thus effectively
a reserved keyword.
lcm-gen:
C++:
- don't try to dynamically resize fixed-size arrays (re issue #42)
Python:
- bugfix in decoding multivariable arrays
lcm-logplayer-gui:
add command line parameters to:
- start logplayer with the log paused
- filter out specific channels from being played back by default.

Best Regards,
Albert
