chore(deps): update angular, rxjs, store

[laurelnaiad]

(I realize this might not be needed, but if anyone needs a version compatible with angular rc.0/rxjs beta.6, I think this ought to work.)

• angular updated to ^2.0.0-beta.17 ^2.0.0-rc.0
• rxjs updated to ^5.0.0-beta.6
• @ngrx/store updated to ^1.4.0 ^1.5.0
• reflect-metadata allowed to float from ^0.1.2 upward
• zone.js allowed to float from ^0.5.15 ^0.6.12 upward

(The last two changes for reasons that the versions/ranges that angular requires should be the versions used here.)

• update LogMonitor template for syntax

(I've added a commit to the PR to move to rc.0)
