lb_preparation not defined (and some other stuff)

Hi Ladybug team,

I just seem to bump into different issues with honeybee lately. Please see attached definition to check if these problems occur:

1) Latest changes in Github did not show up when updating Hb using the component - had to download directly and overwrite files.

2) Colorsurfaces component returns this: Solution exception:name 'lb_preparation' is not defined. I don't remember this being an issue earlier but now it won't go away unless I plug a slider to 'stepsOfSimulation' and then unplug.

3) PETrecipe component returns this: Solution exception:global name 'Icl' is not defined. Goes away if value is unplugged from clothinginsulation @ bodycharacteristics component.

4) AdaptRecipe component returns null for outdoor case with minimal inputs (worked fine earlier)

5) Decompose EPmaterial: the last value (visual absorbance?) is missing from comments

and a less technical question (so that I won't flood the forum with more threads): Can ecoroof material be used to simulate grass on ground? I did an experiment and I got higher surface-temp results than concrete and no indications of shadow effect from obstacles. I'd post this def. but I bumped into the above problems.
