Bump version to 10.8.0 prealpha

[phil-davis]

Description

There are changes to oC10 apps that need to depend on core code later than 10.7.0. We need to start being able to set core min-version to 10.8, because that will be the next core release version. So bump the core version now to 10.8.0 prealpha

For example, PR owncloud/configreport#146
https://drone.owncloud.com/owncloud/configreport/1368/4/3

  App "Admin Config Report" cannot be installed because the following dependencies are not fulfilled: ownCloud 10.8 or higher is required.

Note: changelog not needed. This is a technical "alpha" version bump for development purposes.

If someone notices this tonight and approves, then please merge. That way the daily-master tarball will be built with 10.8.0 alpha tonight.
