Some new comics

Here are some new comic modules:

* AlphaLuna (english and spanish)
* BrentalFloss with 2 submodules (BrentalFloss/FlossedInTime and BrentalFloss/GuestComics)
  * Flossed in Time is not working, since the image URL contains a newline. This could be fixed by providing a imageUrlModifier in Dosage (like the prevUrlModifier) - Do you want me do build that and send another pull request?
* ShadowGirls
* Since EerieCuties was there, I added some other comics by Pixie Trix Comix:
  * MagickChicks
  * DangerouslyChloe
  * MenageA3 (ma3comics.com, adult!)
  * StickyDillyBuns
* Namesake (tried a reasonable file naming here...)

PS: I remember the comics in Dosage were sorted alphabetically once, but not anymore. I tried to put the new ones at the best place I could find... :confused:
