server plugin installs 1.12.1; won't install 1.12.2 about emsm HOT 3 OPEN

... and when I deleted the server/minecraft forge 1.12/ directory and re-ran the updater, it failed with this message:

EMSM: Uncaught exception:
 > Exception: ServerInstallationFailure

 > Message:   The installation of the server 'minecraft forge 1.12' failed. The installation of the server 'minecraft forge 1.12' failed. Installer returned with '1'.

The above exception was the direct cause of the following exception:

Sorted it. The server plugin (via conf/server.conf) expects the 'installer' jar, i.e.

[minecraft forge 1.12]
url = http://files.minecraftforge.net/maven/net/minecraftforge/forge/1.12.2-14.23.5.2768/forge-1.12.2-14.23.5.2768-installer.jar

The fix is, I presume, to update line #877 of core/server.py

from emsm.

Updated, and pushed to GitHub. Just waiting for PyPi login from @benediktschmitt
