Update dependencies

[aivus]

I think, dependencies update are required.

Also, I get bower question, when I trying install app:

Unable to find a suitable version for angular, please choose one:
    1) angular#1.2.29 which resolved to 1.2.29 and is required by angular-cookies#1.2.29, angular-route#1.2.29
    2) angular#~1.3.15 which resolved to 1.3.20 and is required by web-scraper
    3) angular#1.3.20 which resolved to 1.3.20 and is required by angular-resource#1.3.20
