Extracted NuGet tools path to a build property.
Moved some build parameters to top of build file.
Parameterized NuGet package name,

but since Hyprlinkr has no Glue Libraries that depends on Hyprlinkr, I'm
not completely sure if this actually works...
Extracted variables to separate config file,

which hypothetically opens up for using a shared BuildRelease file across
multiple projects.
Changed property name to more descriptive name,

although NuGetPackageDependencyRoot also sounds rather cryptic. The idea
is that you may have a root package, which other, glue libraries or
anciliary libraries may depend upon.
