[geany/geany-plugins] 91cc09: projectorganizer: Create a copy of GeanyWrapLabel and use it for preferences

Branch: refs/heads/master Author: Jiří Techet techet@gmail.com Committer: Jiří Techet techet@gmail.com Date: Wed, 11 Dec 2024 14:21:24 UTC Commit: 91cc097de2a3eb928b1ad3335bba728da17b14b3 https://github.com/geany/geany-plugins/commit/91cc097de2a3eb928b1ad3335bba72...

Log Message: ----------- projectorganizer: Create a copy of GeanyWrapLabel and use it for preferences

The explanation string in preferences is long, separated by \n which makes things hard for translators and makes the dialog wide under some locales.

Since GeanyWrapLabel is not exported by Geany to plugins, create its local copy (and rename it to be sure that it doesn't clash with anything).
