allow server to be started without a solution in folder mode
Bump version 3.3 -> 3.4
Remove package version from source code

It was a pain to update, and not needed any longer, see this quote my
@milkypostman:

    MELPA generates a version number based on the last commit date to
    any relevant file. Melpa-stable uses the version from the tag. It's
    up to you if you update the version number but when you gave a
    version it's probably proper form to still change the version number
    for those who may download the actual zip package manually outside
    of MELPA.

Revert "Remove package version from source code"

This reverts commit 01763b3aa13613cfd6abd2ff4b8d7b883570b81c.

Looks like the version is required by package utilities still.
