Allow overrides definitions using strings instead of symbols
[DEB] Replace invalid characters with underscores

The previous replacement character, dashes, hold special significance in 
the Debian package spec.
[DEB] replace dashes (-) to tildes (~) in version

Dashes hold special significance in the Debian package versions. Versions
that contain a dash and should be considered an earlier version (e.g.
pre-releases) may actually be ordered as later (e.g. 12.0.0-rc.6 >
12.0.0). We'll work around this by replacing dashes with tildes.

Fixes #396

replace dashes (-) with tildes (~) in deb package version numbers
[RPM] replace dashes (-) with tildes (~) in version

RPM 4.10+ added support for using the tilde (~) as a way to mark
versions as lower priority in comparisons. More details on this
feature can be found here:

  http://rpm.org/ticket/56

Replacing dashes with tildes will ensure pre-release versions (e.g. 
12.0.0-rc.1) get sorted before final versions (e.g. 12.0.0).
