Ignore errors from nmake, we expect some right now

This change is already pushed.

Right now, we always get this error when trying to build the installer:

        light -notidy -nologo -cultures:en-us -ext WixUIExtension -out
..\build\x64\adblockplusie-0.8.500-en-us-x64.msi
..\build\x64\adblockplusie-0.8.500.wixobj
..\build\custom_WixUI_InstallDir.wixobj -loc en-us.wxl
C:\Users\fhd\Projects\adblockplusie\installer\adblockplusie.wxs(216) : error
LGHT0204 : ICE80: This 32BitComponent AdblockPlus32.dll uses 64BitDirectory INSTALL FOLDER
NMAKE : fatal error U1077: '"C:\Program Files (x86)\WiX Toolset
v3.6\bin\light.EXE"' : return code '0xcc'
Stop.

However, it's still being build properly. Eric said this issue has already been
addressed in an as of yet unreviewed change, but for now I added this
workaround. We should definitely.

@Eric: Can you link the review in question here? We should definitely do it

IMHO this isn't the right approach. Note that I reverted your change in
https://hg.adblockplus.org/adblockplusie/rev/990fe57c1ba9 - ignoring all errors
isn't great, we should only ignore the errors from a specific light command.
nmake allows doing this by prefixing the command with a dash which is what I
have done.

Ah, I wasn't sure how to do that, so I went for this blunt approach. I won't
miss it :)
