Prevent multiple transitions (only transitions by Navigation)

[nashcft]

Issue

• close Prevent multiple transitions #306

Overview (Required)

• wrap onClick callbacks that run a transition by Navigation with dropUnlessResumed
• replace handleOnClickIfNotNavigating with dropUnlessResumed

Note

• I didn't apply dropUnlessResumed to all click events that run a transition because the safeguard by the function doesn't work for the transition that launches an Activity. You can check the behaviour on the About screen by clicking an item in the Credits section and one in the Others section (except Settings) simultaneously.
