Project Interdependencies, creation and visualization

[#1]

Description - Create project interdependencies through tasks without deleting the tasks

Why is this feature important to you - A proper solution would avoid redundant issue creations and demonstrate relationships between projects better. It may also provide ability to visualize dependencies in an easy to understand way.

How would you like the feature to work - The task not be deleted from the task list after its conversion to a project, or create the ability to relate a task to a project.

Current Behaviour - The only means to create relationships is through issues. When a task is converted to a project, the task is deleted from the task list.
