Make library to be the first column in the details view.

There are two reasons for this change:
1. When allocations are grouped by library, it is nice to have
the library in the first column immediately signifying the grouping.
2. The first column is always left aligned on some platforms (Linux).
This is not the right alignment for showing numbers (they should be
right aligned).
