Export js/css/php format-settings

### Description

Netbeans has an option to export settings and import them into other instances.
There is also an option to export format settings, which is good if collaboration. Unfortunately there is only a global setting and a setting for java, bot all other languages are missing.
If you try to export the formating for e.g. php or js this does not work. There is no obvious option to export those settings.

### Use case/motivation

Working in groups and using git/mercurial needs format guidelines, otherwise the code is changed every release. In order to keep that sync, it would be a good thing to get these settings exported.

No files or tests are named. Start by locating NetBeans' settings export/import entry points and the existing format-settings export for Java, then trace how language-specific formatter settings are selected. Done means format settings for JavaScript, CSS, and PHP can be exported and imported alongside the existing global and Java settings.
