* Changed behavior of `readJournalFiles` to be identical to `readJournalFile` for singleton lists

* Add 'isAssignment' and 'assignmentPostings' to Hledger.Data.Posting and Transaction
* Implemented 'balanceTransactionUpdate', a more general version of 'balanceTransaction' that takes an update function
* Fixed test cases.
* Implemented balance assignment ("resetting a balance")
* Add assertions to show function
* updated the comments
* numbering is not needed in journalCheckBalanceAssertions
* remove prices before balance checks
* rename functions
hledger-lib had a valid install plan with GHC 7.8, but requires GHC 7.10 to compile (currently).
Require base 4.8+ everywhere so that stack/cabal will enforce a supported GHC version early.
Also, bump hledger-ui's "stability" to "stable".
Generated package.yaml files from the old cabal files with hpack-convert,
removed some problematic blank lines manually,
regenerated the cabal files from the package.yaml files with hpack.
Tests pass, looks like all the info is still there.
This means that from now on, we don't edit cabal files directly.
We edit the less verbose package.yaml files. stack will update
the cabal files automatically (or non-stack users can use hpack).
The changes to both are committed, as we still want to provide
the cabal files to downloaders.
Timedot is a plain text format for logging dated, categorised
quantities (eg time), supported by hledger. It is convenient for
approximate and retroactive time logging, eg when the real-time
clock-in/out required with a timeclock file is too precise or too
interruptive. It can be formatted like a bar chart, making clear at a
glance where time was spent.
The regex helpers were converting strings to regex-tdfa regular
expressions on the fly every time, but this appears to be quite
expensive. The simplest memoisation lib seems to solve it nicely.
The --format option's OutputFormat type was named confusingly like the
--output-format option. It has been renamed StringFormat to distinguish
it from StorageFormat (aka the data file format, referenced by
--output-format). Related code and types have been consolidated.
Also the (single-column) balance report's item rendering has had
some cleanup.
Here are hpack package.yaml files for the other hledger cabal files.
These remove a lot of human-error-prone duplication.
They are not used yet as hpack isn't quite mature enough -
when it supports flags and benchmarks we will probably switch.
