package name length limit not enforced

[einar-hjortdal]

Describe the bug

The only thing enforcing a package name character length limit is maxlength=10 on the html input element. This can be easily bypassed.

Expected Behavior

The handler should check and reject packages with names that exceed the limit.

Current Behavior

The limit can be bypassed, see bandsintown

Reproduction Steps

submit a custom payload

Possible Solution

Enforce limits in the handler, not at the html level.

Additional Information/Context

I think the limit of 10 characters is too short.
In the package I submitted, the brand name is 11 characters long. I can't just truncate the name to bandsintow and I can't just use a different name because people are going to look for the brand name, not something else.
Raise the limit to something more reasonable.
