Create list of all possible types and syntaxes

[provokateurin]

To ensure users don't run into problems this tool should cover all possible types and syntaxes. This is not the case so far, so a list of all possible types and syntaxes should be created. Afterwards the missing types and syntaxes should be implemented. The list can probably be compiled by reading through the psalm and phpdocumentor docs.

All missing syntaxes and types should be implemented and tested, but for the ones we already implement it needs to be ensured that they are tested as well.
Might be time for setting up coverage checking when running on the test app.
