[development] Modules page rework

[Moshe Weitzman]

looks like a big improvement to me. if you are into experimenting, i would 
try this out with just a table and no fieldsets. use subtabs for things like 
'contrib', 'installed'. the default should show lots of modules i would 
think, like today.

yeah, i think this can go.

um, version is one of the main benefits of this. i like being able to look 
at my installed modules and then http://drupal.org/project/Modules and see 
if i am up to date.

i'm all for metadata and ini format. jjeff is over here asking for icons for 
  modules. even a tiny icon and a big icon. i reckon those would be metadata 
fields.

personally, i think i like alpha by package first.

as for 'drupal core', i think you want to follow the lead of the installer. 
i think even the word 'drupal' is a variable pointing to the name of the 
install profile.
