The Base64 package previously had extremely basic functionality. It only
suported the standard encoding character set, didn't support line breaks
and always padded output. This commit makes it significantly more
powerful.
The FromBase64 impl now supports all of the standard variants of Base64.
It ignores newlines,interprets '-' and '_' as well as '+' and '/' and
doesn't require padding. It isn't incredibly pedantic and will
successfully parse strings that are not strictly valid, but I don't
think the extra complexity required to make it accept _only_ valid
strings is worth it.
The ToBase64 trait has been modified such that to_base64 now takes a
base64::Config struct which contains the output format configuration.
This currently includes the selection of character set (standard or
url safe), whether or not to pad and an optional line break width. The
package comes with three static Config structs for the RFC 4648
standard, RFC 4648 url safe and RFC 2045 MIME formats.
The other option for configuring ToBase64 output would be to have one
method with the configuration flags passed and other traits with default
impls for the common cases, but I think that's a little messier.
FromBase64 still kills the task if you pass it invalid input, which isn't
particularly appropriate for a function into which you'll be passing
unvalidated input. Would it be worth changing its signature to return a
Result?
This fixes a segfault when configuring rust to use local-rust-root. The
libraries were renamed in the 0.6-0.7 transition, and the script was not copying
them all. I also removed the line referencing libcore (now libstd).
There's now an enum to pick the character set instead of a url_safe
bool.
from_base64 now returns a Result<~[u8], ~str> and returns an Err instead
of killing the task when it is called on invalid input.
Fixed documentation examples.

Adds a lint for `static some_lowercase_name: uint = 1;`. Warning by default since it causes confusion, e.g. `static a: uint = 1; ... let a = 2;` => `error: only refutable patterns allowed here`.
I think it's WIP - but I wanted to ask for feedback (/cc @thestinger)
I had to move the impl of FromIter for vec into extra::iter because I don't think std can depend on extra, but that's a bit messed up. Similarly some FromIter uses are gone now, not sure if this is fixable or if I made a complete mess here..
