gio-tool: Various fixes related to error messages

This patch contains the following changes:
- Print all errors with "gio: " prefix
- Print file uri in error for each tool allowing multiple locations
- Mark all error messages translatable
- Do not leak strings used in error messages
- Always start error messages with capital letter
- Unify some error messages across various tools
- Fix addional/missing new line characters
