Remove LabEnv references to Reggie

[olle]

LabEnv uses some css and javascript files from old versions of Reggie, but these should be renamed, to avoid confusion. Eventually these files should be cleared from Reggie-specific resources, that are not used in LabEnv.

1. Resource names in these files referring to Reggie/reggie should be changed to refer to LabEnv/labenv instead.
2. References to Reggie version number (currently unused in LabEnv) should be changed to LabEnv version number, and it should be displayed in the right part of the form header, like the version number is displayed in Reggie.

Disclaimer: This update does in no way change the fact that much of the user interface and functionality in LabEnv was inspired by Reggie.
