[pbs-devel] [PATCH widget-toolkit 2/2] window: edit: added `convertNewlines` config

[Gabriel Goller <g.goller@proxmox.com>]

When setting `convertNewlines` to true, all the '\n' will
be converted to '<br>' tags and vice-versa. This means we
can press enter in a `textfieldarea`, save the config and
we get a '<br>' in the config file. When editing the value,
the '<br>' will be converted back to a '\n'.

Note: Implemented to close #4589 (support multi-line comments)
