Support reading the subject from a file. (#173)

Browse Source 
Allows dynamic subjects to be generated at action runtime
(e.g., "Foobar version 1.2.3 is released", where 1.2.3
is not known at action config time).

Leverages the existing file:// support for body, but renames
getBody to getText, in keeping with this expanded role.
