[LAU] Minor bug-fixes and accessibility improvements of GSequencer 0.6.23

Hi all Advanced Gtk+ Sequencer release 0.6.23 has defenitily not to be missed. Fixes done so far: * fixed allocation of AgsDial * fixed focus in ags_dial.c * fixed _File mnemonic in menubar * fixed recover of GSequencer project as doing properties * fixed SIGINT while reading XML files including AgsRecallLadspa see ChangeLog for indept view. Further on http://gsequencer.org is an empty project with one drum and two synths connected by a mixer with output panel. So you just have to fill in the gaps. Further the mixer is using LADSPA caps plugins: * drum -> 10 band equaliser * matrix0 -> Mono Phaser * matrix1 -> Noise Gate Would be great to hear from you ... $ wget -c http://gsequencer.org/ags_drum_and_synth.xml $ gsequencer --filename ags_drum_and_synth.xml cheers, Joël
