Also fix various variable names to consistently indicate which strings
contain HTML.
Some of these changes close cross-site scripting vulnerabilities, and
others are for consistency. It’s important to be meticulously
consistent about escaping so that changes that would introduce
vulnerabilities stand out as obviously wrong.

* lint: Implement HTML Linting with htmlhint and fix indent.
Implements HTML linting using htmlhint and uses
indentation rules of zulip webapp - 4 spaces.
Creates a separate file .htmlhintrc for the rules, most
of which are defaults. Also, fixes indentation in html
files and adds a missing title in about.html.
* deps: Change versioning of various dependencies to exact versions.
As we prefer to use exact working version
for dependencies, changed the versions to
exact versions.
Fixes#676.
