Refactor configurations handling:

- rearrange compile call parameters for clarity, more defaults
- remove baseConfiguration method - it is now covered by defaultConfiguration
for static part, and refineConfiguration call if a config parameter is
specified
- implement proper configurations chaining, documented in comment to compile function
- minor renamings and refactorings
