Thanks.

Closes: #552

Shame on me

Makefile.am: Add the syntax files, valgrinds false positive suppressions, make nicificator to the tarball

(p_symbols and vlc_symbols.h sucks time, heh? - use shared libvlc/libtool)

- Fix memleak in case of connection failure

* Use the proper parent object to do var_Get macosx-black on. Fixes the issue where we failed to mutex_lock.

deserializing floats from configuration (fixes #589)

I know this is NOT the “right” way to fix this.
The “right” way would be to remove floats from the configuration...
but there are approximately one float parameter in the core and 46 ones
in our current plugins set, none of which I use myself. So I am
defintely not going to rewrite all^H^H^Hany of them.

Of course, it would be cleaner to be “strict”  in what we write to
the configuration file, than “liberal” in what we accept... but IMHO,
it is way easier and more robust to be liberal in what we accept in
this particular case (ie. accepting both decimal separators is trivial,
while serializing float numbers manually is complex).

You can definitely declare variable at the beginning of a nested block with gcc 2.95

* put a warning to prevent users from reporting known bugs for panel is which won't be included within 0.8.5
* fixed svn propset

all: reworked gui layout of dialog boxes to get rid of the dark gray background colour (I hope that wasn't intentional :)

all: for Cygwin, make sure that the program-prefix is empty, so that libgcrypt-config & gnutls-config are not prefixed by the target build (i586-mingw32msvc), which causes prevents configures scripts from detecting them
