[TASK] Removing unused argument "bullet"

The argument bullet designed to insert html before each item, but this is a rare use case especially because there are alternatives fx by css or manual rendering.

Since the functionality for this argument is not yet implemented we will remove the argument.

Who needs something like that should use the manual rendering instead.

[TASK] Make "b" argument on math.minimum and .maximum optional

When "a" is an array, max() and min() will work with just the array as argument. The ViewHelper, however, required a "b" argument which could never be NULL and thus prevented using only the "a" argument.

[FEATURE] Cookie-less domain prefix setting

This commit adds a `plugin.tx_vhs.settings.prependPath` setting which when used is inserted in front of all (relative) asset paths - including those returned by VHS's image ViewHelper and relative resource path ViewHelpers. In addition, the ViewHelper `v:page.prefixPath` ViewHelper is added which outputs this setting's value so it can be used with other ViewHelpers like `f:uri.image` or `f:uri.resource`.

This setting has precedence over VHS's respect for `config.absRefPrefix` which means it is capable of containing a secondary domain name and protocol, allowing all URIs built for assets to _use a cookie-less domain name for all asset paths_. Doing this is generally considered a good idea since it allows requests to that domain to set and receive no cookies and thus be smaller and faster to process.
