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.

-:AlignCommodity     Adds spaces between an account and commodity so that the
-                    decimal points of the commodities all occur in the column
-                    given by |g:beancount_separator_col|.  If an amount has no
-                    decimal point, the imaginary decimal point to the right
-                    of the least significant digit will align.

-                    The command acts on a range, with the default being the

-                    range and to the right of the account name, the cursor
-                    will be pushed to the right the appropriate amount, so
-                    that it remains on the same character.
