Subject: Replace AlignCommodity with bean-format

AlignCommodity replicates the functionality of the bean-format command
that is shipped with beancount itself. Therefore, we can fully replace
it by having vim invoke bean-format through formatprg.

Even though bean-format's output might differ from AlignCommodity in
significant ways, we feel that using one unified tool is superior to
having several (possibly incompatible) custom implementations. That way,
if bean-format is improved upon in the future, all downstream consumers
profit. For regular usage, however, this change should be transparent.

Note that while bean-format supports a few different ways of formatting
the ledger, we have opted to hard-code one specific setting. This will
match the default behaviour of fava, aligning currencies in column 61.

Managing the arguments passed to bean-format dynamically is considered
out of scope, especially given the fact that the user need only override
formatprg to get a custom setting.

This commit will also drop the g:beancount_separator_col variable and
the tests for AlignCommodity. Ideally, testing will now done upstream
for bean-format itself.
