Doc: Usage - Updated 'Running LilyPond' introductory paragraphs

Issue 4602

A small re-write of the first two
section introductions and change
or node names with an effort to
make the information for the
different OSes more prescriptive.

Also made more of a distinction
between running LP 'normally' via
a GUI and the command-line. This
will hopefully point new users in
the right direction for those
Fron-end applications (like
Frescobaldi) if they jump straight
to this manual first.

Since Frescobaldi has an "Engrave (custom)" function which allows the use of
these command-line options, basically a command-line embedded in a GUI, maybe
reword this as: "allows configurable options to be applied to the output."

Since these helper programs are also available in Frescobaldi, maybe reword this
last bit to something like: "which are available via the command-line."

Thanks, I'm still struggling to get this to make doc with the 'ca' translations
(it is only those that seem to break with my changes and I cannot yet work it
out).

Done.

You don't appear to have changed the menus in the translations, but I would
strongly recommend leaving all the translations to the translators - unless you
can translate the modified headings into Czech and Japanese.
