fix(ngResource): correct leading slash removal.

Fixed an issues with ngResource param substitution where it was incorrectly removing leading slash when param was followed by a non-slash character.
Ex:
'/:foo/:bar.baz/:aux'

params = {
  foo: 'aaa',
  bar: undefined,
  aux: undefined
}

The above params were incorrectly producing '/aaa.baz' but now it results in '/aaa/.baz'.
feat(directive): added ng-open boolean directive

Closes# 1797 add ng-open attribute
feat(route): Allow using functions as template params in 'when'
feat(scenario): add mouseover method to the ngScenario dsl
fix($resource): Route constructor, updated RegExp

Update RegExp to allow urlParams with out leading slash (/).
- Will allow reoucese to be loaded from a relative path

Example:
var R = $resource(':path');
R.get({ path : 'data.json' });

Example usage:
Load resources in applications not using webserver, ie local webapp in on a tablet.
docs(contribute): adding npm install to step-by-step

npm install is listed in the dependencies section of the contribute guide but
is missing from the step-by-step. This adds it as step 4.
docs(jqLite): fix typo
chore(Rakefile): skip build parallelization on Travis

Due to a infrastructure change on Travis starting JVMs in forked
processes doesn't currently work. Since we don't really care that
much about the build speed on Travis, I'm going to disable it there.

fix(angular.equals): relax the comparison for undefined properties

in 5ae63fd3 the comparison was made consistent but strict, so that

angular.equals({}, {foo: undefined}) // always returns false

this turns out to cause issues for data that is being roundtripped via network
and serialized via JSON because JSON.stringify serializes {foo: undefined} as {}.

Since angular.equals() behaved like this before the 5ae63fd3 in 50% of the cases,
changing the behavior in this way should not introduce any significant issues.

Closes #1648
