Keypair import should tolerate CR & LF

[justinsb]

Keypair import shouldn't fail if a CR or LF makes its way into the string, e.g. because you copied and pasted from a shell.

Simply strip them out; they can't be in a key anyway (I think)...

    Removed new lines when importing a keypair

    Fixes bug 988139

    All new lines (\r, \n) are removed from input
    when importing a keypair. This is done as sometimes
    a user copies the public key from terminal, with
    new lines in it. As new lines are not allowed in
    a public key, so they are stripped.
