Rewrote powershield event, adding a new "Laser Height" option.

Fixed the 'build_linux.sh' shell script when the iso path contained spaces. @ramirez7

Bugfixes

Fixed issue where the ledgedash event would not reset after the HUD stopped updating.
Fixed "Act Oo Hitstun" OSD for grounded (sakurai) hitstun. This OSD now works for acting out of falco's laser (for the first two frames, at least).
"Counter After Frames" and "Counter After Hits" now work (mostly) when "CPU Counter" is set to "On CPU Hit".
The CPU will now start grounded when set to a getup attack option in "Reversal Training".
"CPU Counter" in recording options now triggers on shield hits.
Fixed play slot counter actions desync when the slot made the cpu airborne.
Infinite shields option now applies to nana.
