1. For every resource set, create a matching "generated" resource set.
The generated sets have the same relative priority as normal ones, but
they have lower priority then all normal sets (so no generated file ever
overwrites a checked-in one).

2. Introduce a third type of a DataFile, where one data file is a source
to multiple data items that correspond to generated files (PNGs).

3. When normal sets find a file that will be replaced by generated
files, they just hand it off to the matching "generated set".

4. The usual DataMerger machinery determines which data items should end
up in the final resource directory (no changes here).

5. The PNGs are generated on-demand in MergedResourceWriter, which means
only needed files are generated. They are then crunch-copied to the
final directory, which contains all the files.

I was quite surprised to see this test fail. Turns out, if /tmp/foo
exists and is a directory, the conversion to/from URL will append a
slash at the end, which breaks some test cases.

https://android-review.googlesource.com/159472 broke
HtmlBuilderTest since \ns are no longer added. Removing
them from the test as well.

In IntelliJ (Studio), when displaying a sheet-style dialog on mac,
SheetController converts \n to <br/>, resulting in extra line breaks.
Removing the \ns added by HtmlBuilder, since they shouldn't make any
difference to a well-behaved renderer anyway.

This improves the performance a lot, and SVG spec actually says that DTD is
not recommended.
