Update Script for 2.5.1

[maxgr21]

Hey There,

it seems the install.sh script has not been updated for the new Version of MISP.

If it is not too much trouble, would it be possible to update it? It is not compatible as the CakeResque was removed from version 2.5 onwards (https://github.com/MISP/MISP/releases)

Curently getting the following error during installation:

Error:
sed: can't read /var/www/MISP/app/Plugin/CakeResque/Config/config.php: No such file or directory
Error: Line 1268: exiting with status 1

Yep, can confirm, it's still the case with 2.5.3.
