Multiple hooks in the same plugin directory were overwriting each
other's stdout.log, stderr.log, hook.pid, and cmd.sh files. Now
each hook uses filenames prefixed with its hook name:
- on_Snapshot__20_chrome_tab.bg.stdout.log
- on_Snapshot__20_chrome_tab.bg.stderr.log
- on_Snapshot__20_chrome_tab.bg.pid
- on_Snapshot__20_chrome_tab.bg.sh
Updated:
- hooks.py run_hook() to use hook-specific names
- core/models.py cleanup and update_from_output methods
- Plugin scripts to no longer write redundant hook.pid files
