*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.

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)

improved icons and added ability to open patches by dragging and dropping or double-clicking on the patches within nautilus
