# Link to a Label
#
# label - Label object to link to
# project - Project object which will be used as the context for the label's
# link. If omitted, defaults to `@project`, or the label's own
# project.
# block - An optional block that will be passed to `link_to`, forming the
# body of the link element. If omitted, defaults to
# `render_colored_label`.
#
# Examples:
#
# # Allow the generated link to use the label's own project
# link_to_label(label)
#
# # Force the generated link to use @project
# @project = Project.first
# link_to_label(label)
#
# # Force the generated link to use a provided project
# link_to_label(label, project: Project.last)
#
# # Customize link body with a block
# link_to_label(label) { "My Custom Label Text" }
#
# Returns a String
