Bump handlebars from 4.0.12 to 4.1.0

[dependabot]

Bumps handlebars from 4.0.12 to 4.1.0.

Changelog

Sourced from handlebars's changelog.

v4.1.0 - February 7th, 2019

New Features

• import TypeScript typings - 27ac1ee

Security fixes:

• disallow access to the constructor in templates to prevent RCE - 42841c4, #1495

Housekeeping

• chore: fix components/handlebars package.json and auto-update on release - bacd473
• chore: Use node 10 to build handlebars - 78dd89c
• chore/doc: Add more release docs - 6b87c21

Compatibility notes:

Access to class constructors (i.e. ({}).constructor) is now prohibited to prevent
Remote Code Execution. This means that following construct will no work anymore:

class SomeClass {
}

SomeClass.staticProperty = 'static'

var template = Handlebars.compile('{{constructor.staticProperty}}');
document.getElementById('output').innerHTML = template(new SomeClass());
// expected: 'static', but now this is empty.

This kind of access is not the intended use of Handlebars and leads to the vulnerability described in #1495. We will not increase the major version, because such use is not intended or documented, and because of the potential impact of the issue (we fear that most people won't use a new major version and the issue may not be resolved on many systems).
