Implement compilation of regexes at creation time

This means that the verification of the correctness of the regex is
done once, at the deserialisation/creation time, as in the Python
code. To do this, we have to change the FilterRegex type from an alias...

Parameterize the Filter type

In preparation for introducing filtering functionality, we convert the
'Filter' type from a '*' kind to a '* -> *' kind.

This allows us to define some general properties for the filter, and
for example introduce later an easy filter compilation, etc....

Adding allocList function

This function iterates over the tryMGAlloc function, updates the node
list and instance list, and refeeds it recursively until no new
instances are left.

This allows us then to allocate multiple instances and see if they would
fit together....

Improve error reporting in our JSON conversions

Reporting things such as the following in our error messages
(indentation added by me, not originally present, so it's even worse):

JSArray [JSArray [JSRational False (1 % 1),JSString
                    (JSONString {fromJSString = "a"})],...

Fix qualified import of Data.Map in QC.hs

Data.Map, leaving to longer names. Let's make it similar to the rest
