add "fieldnames" query param for GetProjectFiles/GetProjectChunkInfos (#29)

- Improvement: It is now possible to control which fields to include in `/prj/{project}/oplog/{log}/chunkinfos` request by adding a comma delimited list of filed names for `fieldnames` parameter
  - Default fields are: `id`, `rawhash` and `rawsize` (translates to `?fieldnames=id,rawhash,rawsize`)
  - Use `?fieldnames=*` to get all the fields
- Improvement: It is now possible to control which fields to include in `/prj/{project}/oplog/{log}/files` request by adding a comma delimited list of filed names for `fieldnames` parameter
  - Default fields are: `id`, `clientpath` and `serverpath` (translates to `?fieldnames=id,clientpath,serverpath`), `filter=client` only applies if `fieldnames` is not given as a parameter
  - Use `?fieldnames=*` to get all the fields
