Make these modules' names more like the heavily-used types they
define (CliOpts, UIOpts, WebOpts). This is consistent with
RawOptions and ReportOptions, and helps with code navigation.
The balance command's --format option (in single-column mode) can now
adjust the rendering of multi-line strings, such as amounts with multiple
commodities. To control this, begin the format string with one of:
%_ - renders on multiple lines, bottom-aligned (the default)
%^ - renders on multiple lines, top-aligned
%, - render on one line, comma-separated
Also the final total (and the line above it) now adapt themselves to a
custom format.
We should now read all text in universal newline mode, so eg journal
files with DOS/windows line endings are fine.
This also deprecates and disables our IO encoding compatibility layer,
which prevented many encoding-related problems with certain platforms
and GHC versions. With modern GHC (7.x) this is now hopefully totally
unnecessary, but the module remains in place just in case.
