bug#25709: 24.4; erc-accidental-paste-threshold-seconds defaults to nil

[Phil Hagelberg]

When using ERC with the default settings, it allows you to spam the
channel with lines accidentally pasted in. A feature exists to prevent
this disruptive behavior, (erc-accidental-paste-threshold-seconds) but
unfortunately for some reason it is disabled by default. Fixing this
would save ERC users some embarrassment when they mistakenly
middle-click. I have found that 0.2 is a good value which will catch
accidental pastes but not interfere with legitimate usage.
