as of v0.10.6 this is not the case any more
fix(date):  invert timezone sign and always display sign

This commit fixes #1261 and #1532. This covers
two separate issues:

- Positive timezones were being formatted without
a leading `+` resulting in a formatting string
like: "HH:MM:ssZ" giving "12:13:141000" instead
of "12:13:14+1000". Fixed by checking if timezone
is > 0 and adding a leading "+".

- Timezone output signs were inverted.
mock.TzDate expects the timezone _offset_ as it's
first argument, _not_ the timezone. This means
that a mock.TzDate with a positive offset should
result in a date string with a negative timezone,
and vice-versa.

Closes #1261, #1532
fix($cookies): set cookies on Safari&IE when base[href] is undefined

Safari and IE don't like being told to store cookies with path set to
undefined. This change ensures that if base[href] (from which cookie path
is derived) is undefined then the cookie path defaults to ''.

The test verifies that the cookie is set instead of checking that cookie has correct path,
this is due to that cookie meta information is not avabile once the cookie is set.

Closes #1190, #1191
fix($compile): rename $compileNote to compileNode

Directives was observing different instances of Attributes than the one
that interpolation was registered with because we failed to realize
that the compile node and link node were the same (one of them
was a wrapper rather than raw node)

Closes #1941
fix(scenario): include error messages in XML output

Fix the XML output of scenario tests so that it properly includes error
messages from failing specs.
docs($q): fix typos
fix(angular.forEach): correctly iterate over objects with length prop

Should handle JQLite, jQuery, NodeList and other objects like arrays
but not other generic objects or instances of user defined types
with length property.

Closes #1840
refactor(angular.copy): use slice(0) to clone arrays

slice(0) is way faster on most browsers
refactor(angular.copy): use array.length=0 to empty arrays
chore(docs): improve docs parser type

previously we barfed on function type definition with optional arguments
like {function(number=)}

this fixes it

I also added a bunch of code that helps to debug incorrectly parsed docs.
revert: refactor(angular.copy): use slice(0) to clone arrays

This reverts commit a5b3bcf41cb0e3130439666a78a0ba9feadbd84a.

slice(0) doesn't perform deep copy of the array so its unsuitable
for our purposes.
test(angular.copy): add tests for scenarios when target is missing
docs($resource): fix missing punctuation
chore(Rakefile): parallelize the build on Travis

now that the forking issue is solved we can run regular build there

docs(guide): Fix typos in concepts/model,view.
fix(numberFilter): fix formatting when "0" passed as fractionSize

When checking to add decimal and trialing 0s number filter used to check
trueness of fractionSize. "0" evaluating to true causes "123" to return "123."
fix(resource): 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.
