Allow relative urls in manifest in WebPackageResolver

[pipe01]

If there's a line like 1.2.3 ./build.zip in http://www.example.com/manifest.txt, the archive URL will be set to http://www.example.com/build.zip.

Hi. Nice improvement, this is actually really useful.
Maybe you can use Uri and use its Relative tag to do this with even less additional code?

[pipe01]

Is that what you mean?

I meant more as:

1. Convert _manifestUrl to Uri and store in a var
2. Parse the package URL and create a relative URI based on the manifest URI. This will take care of all sorts of relative URLs automatically.

That's basically what I'm doing, but without the intermediate variable.

Not exactly, since you wouldn't need to call StartsWith and bother with relative paths. 😛
