For more details, see:
https://code.launchpad.net/~googol/openlp/html-clean-up/+merge/184210

Hello,

I started this sammmmme time ago and just found it...


- removed (outline/shaddow) workarounds from html builder

OS.......Version
----------------
Fedora...537.21
MAC......534.34
Arch.....537.21
Windows..534.34

The workaround were for 534.3 and below, so all major platforms should be ok with this change.
