Trolli Schmittlauch dc2e399d64 protect concurrent node state access with STM 
- for allowing concurrent access to predecessors and successors, the
  whole LocalNodeState is passed wrapped into an STM TVar
- this allows keeping the tests for the mostly pure data type, compared
  to protecting only the successor and predecessor list

Trolli Schmittlauch f8d444d5b6 FediChordMessage: last part has falg instead of parts number in each msg 
Motivation: Including the number of parts in each message part requires
the total number of parts to be known in advance, making dynamic
responses based on the received data difficult

Trolli Schmittlauch e3bfa26ddb join request + large FediChord refactoring 
- implement sending of initial join request sending, response parsing
  and cache population (untested but compiles)
- refactor basic types and their functions into Hash2Pub.FediChordTypes
  to prevent import loops, leaving Hash2Pub.FediChord to contain the
  high level actions called from Main

Trolli Schmittlauch b8eeb852da Merge pull request 'Linting integration' (#17) from Hecate/Hash2Pub:hlint-configuration into master 
Introduce some code formatting guidelines and enforce them with hlint and stylish:

- End-of-line extra spaces removal;
- Import lines ordering;
- Redundant ($) removal;
- Generalisation of (++) and map to (<>) and fmap;
- Preferring pure over return;
- Removing extraenous extensions.

Hécate 41e999ed99 Linting integration 
This commit brings in an HLint configuration file
and several recommended modifications such as:

* End-of-line extra spaces removal;
* Import lines ordering;
* Redundant $ removal;
* Generalisation of ++ and map to <> and fmap;
* Preferring `pure` over `return`;
* Removing extraenous extensions.

And finally, a `stylish-haskell` helper script
that detects if code files are dirty. Can be useful for CI,
although manually calling it can be nice if you would rather
first implement then beautify.
