v1.11.0

HUGE refactor of the library geared towards supporting multiple different formats of batch request and response i.e.
http 1.1 batch, NodeJS, Facebook etc. The library now has the concept of batch adapters which are able to transform raw
http requests and responses into the correct batch formats for a particular server.
Added the default http 1.1 adapter which supports .net / java
Added a node js multifetch https://github.com/debitoor/multifetch adapter which supports fetch a batch of GET requests.
