*further improved naming convention for settings files (default.settings and user.settings), cosmetic improvements to the indexing prompt of the help browser dialog.

*updated file locations and made names more consistent across all folders (everything now uses pd-l2ok instead of pdl2ork). Placed user settings into ~/.pd-l2ork/ folder and renamed to simply settings, placed xapian search database for the browser inside the ~/.pd-l2ork folder.

*removed qt from autobuilds since qt5 is not standard in Ubuntu 12.04 and besides we need to update control files as well as online documentation

*improved installer to make it easier to recompile pd-l2ork when continuing development after building a snapshot deb or tarball installer (the pd folder will retain config script with the appropriate --prefix flag)

made shortcuts more flexible in terms of startup (not forcing JACK, which will help on setups that don't want/need JACK backend), as well as providing intelligent menu shortcuts for ALSA and JACK

hopefully improved libglew support due to unfortunately named libs that limit their flexible rollout across different versions of Ubuntu (and likely other distros as well)
