Now everyone auto-connects to localhost unless passed the
option --connect=
Also make indexer find the logs.conf from the same dir as the
commandline passed config file.
This makes running it as a service more useful.
This adds lots of little things;
* Add GetTransaction API call
* I refactored the GetBlock API a little to reuse code.
* a new 'Version' API call for the hub
* API for the logging manager, so we can set a default
setup with just C++-APIs
* various (usability) fixes in the FloweeServiceApplication
* Binding to localhost attempts to bind to both IPv4 and v6
* Print the actual transaction hex from indexer-cli (which really
is just a testing app)
