Added aggregate `diff` event

• Provide a single diff event for all changes to a SELECT result set from a single binlog event

  Aggregation of added, changed, removed events for current event into a single array for easier handling of multiple changes

Schema filtering enabled on ZongJi module

Improve performance by only parsing fields on rows events that are used in triggers from select statements.

v0.0.7 release notes removed due to error found in upstream ZongJi package. Updated ZongJi package in this release fixes filtering bug.

Upstream PR: nevill/zongji#6

Moved zongji package out of node_modules

NPM does not allow custom files in the node_modules directory

Difference events, result buffering

• Difference events, added, changed and removed have been added. As well as the skipDiff setting.
• Result sets are cached for duplicate queries on update and creation.
