cleanup svg

[waldyrious]

• remove group transform
• use fill attribute instead of style
• more compact code layout
• use tabs for indentation and spaces for vertical alignment

btw @dreeves you might want to replace the inkscape-made logo at https://www.beeminder.com/images/infinibee.svg with this (much shorter and more readable) manually cleaned-up version :)

Done! Thanks so much, Waldir!
