*.ftl is not associated with the Generic Text Editor

[ddekany]

On a new Photon M6 installation. There were some installation warnings, see at the [*]. Syntax highlighting is not happening (text color is just black everywhere), because the file is not opened with
the "Generic Text Editor" (as it's called under the "Open with..." menu), but with the plain "Text Editor". Probably relevant error log entry:

!ENTRY org.eclipse.ui 4 4 2018-03-17 19:04:45.059
!MESSAGE Plugin org.eclipse.lsp4e.freemarker, extension org.eclipse.ui.editors: Unknown editor with id: org.eclipse.ui.genericeditor.GenericEditor

I close this issue because this issue is about eclipse lsp4e freemarker. I have recreated the issue at angelozerr/lsp4e-freemarker#1
