Use full lodash instead of lodash components

This change trims 134 modules from the dependency tree, many of which
were duplicate depdencies between the 4 lodash.function modules used
and their sub-dependencies.

Before:
$ npm ls | wc -l
     494
$ du -sch node_modules/lodash*
 432K   node_modules/lodash.assign
 660K   node_modules/lodash.clonedeep
  96K   node_modules/lodash.defaults
 980K  node_modules/lodash.pick
 2.1M  total

After:
$ npm ls | wc -l
     360
$ du -sch node_modules/lodash*
964K   node_modules/lodash
964K   total
