Allow dotted first level variables on .ini and .properties [was:how to load simple config without sections?]

I have following config sample:
```
#
# Use this file to override default entries in /usr/share/web/WEB-INF/classes/app.properties
#
app.web.serverURL=https://app.host.org
securitySalt=l56MPNX9I1XnTghgkRaCjlxfzyPZJR6zOjCQ3vBF8
```
I can not load it with any parser
