fix broken comittee scraper, workaround complicated BR comittees

[Horrendus]

• Fixes bug #104 (llp in comittes scraper was written in small letters, Loki expected it to be big letters and broke it when fixing some unicode stuff :) )
• Tries to fix bug #47 (by making NR comittees more consistent, they are now always active & by disabling BR comittees [no time to fix them atm, they require a much more carefull handling])

[Horrendus]

Either all Comittees & related data should be deleted and scraped again or the following database changes should be made:

• Delete all BR comittees & related data (they could be inconsistent)
• For all NR comittees set active to True
