NSClient

Added back the WEB UI which is now fully working again

The WEB UI has the same functions as before but is now written in a modern framework. It is still a bit bare bones and I have plans to add configuration wizzards to simplify configuration.

Other Fixes

• Fixed an issue where the config was not read by the installer causing the config to be reset every time you upgraded NSClient++
• Added missing symbols to releases
• Swapped versioning to use semantic versioning
• Automated version bumps

> WARNING! Upgrading from 0.5.x will delete existing config! We are currently looking into fixing this.

Fixed crash in NRPE server

Changes:

• Removed secondary installer The secondary installer was a work around for as it was hard to build NSClient++ but now with automated builds anyone wanting the secondary installer can easily fork and maintain their own
• Fixed script installed in wrong folder Scripts were wrongly installed in the root folder
• Added debug symbols archive To helt debug crashes I have added an archive with debug symbols
