Improve display of templates with long lines for tasks

[Stefan Glase]

As a user I want to have a good overview over the created templates. Long lines shall not break the layout of the table.

Example

- This task has a very long description
  description: this is a very long description with some {n}line breaks and som other styling of *bold text* and other stuff that causes a longer description like this url to the documentation page: https://jira-multiple-subtasks.codescape.de/create-subtask-templates 

Tasks

• implement horizontal scrolling for very long lines in templates (user templates and project templates)
