INI keys can not be read in WorkFlow
When creating an ini file from scratch (for example for MeteoIO) and running it directly (after saving it to a file), the workflow output path can not be read (${key:OUTPUT::METEOPATH} can never be read, it is actually empty). This comes from the fact that MainWindow.getINI() does not contain the same keys as in the INIParser just after saving... If reading an existing file, the problem does not happen.
A dirty fix has been implemented in commit 30f07dd0 but a cleaner solution should be implemented (preventing MainWindow's INIParser from containing a different content than the INIParser that writes the ini file).
