moodss 19.1 (stable) released

Moodss is a modular GUI application that can monitor systems, networks, databases, ... It displays data in graphical viewers, sends emails and execute scripts on thresholds, archive data in a SQL database, and includes a daemon for background monitoring.
This new version allows the user to choose the position of the data cells labels in graphs and bar charts viewers, added threads compatibility and messages to Perl modules, fixed a few bugs and added minor features.

### CHANGES ###
- in moodss GUI:
- added sub-menu in popup menu for graphs and bar charts viewers to choose which side the data cells labels should be placed relative to the graphics
- in preferences and dashboard configuration, in viewers graphs section, added default choice for side of data cells labels
- unexpected command line options could result in a source code trace printout instead of a more elegant error message
- in configuration dialog box, in application background section, tabs of pages, when placed at bottom were clipped: fixed using BWidget bug fix

displayed tables were resized too small

- Japanese help updated
- a module failing to load due to a fatal error could disturb the
configuration of thresholds or database storage on cells belonging to other modules, if the module in error had itself cells set in thresholds or in database storage (note: fixed using additional data in dashboard file, so save over existing dashboard if in doubt)
