Adjusting the trainings-Window to match the new data-model / stucture

Left Column

• Top: T5 sys-message always in blue and Tooltip "This message is added by translate5 and can not be changed" (-> future feature)
• Below: each already sent training appears as own item, that can be opened (see two screens). The caption shall be "Fine tuning", not "Training"
• Below: Prompt(s) = Sysmessage/Example Sets. Each set can be edited as in the prompt management. The "Remove prompt" button will remove the sys-msg and the related example (with confirmation for examplesets already existing on server-side)
• Several sysmessages/examplesets can be added, they appear below each other, the sys-message followed by the example-set with the remove-button in the middle

Right column

• Top: Button to "Add prompt", Opens selector with list of existing sys-msg available with translated examples in the matching language-combination. The similarity of language works by language only, so we offer "en-US" examples for "en" and vice versa. Shown is a grid with name, comment, system-message as tooltip and an "Add" button.
• Remove capabilities to add terminology
• Change message for TMs that these will not show up as examples (just as a hint)

• Future Feature: Button to add an complete empty Sysmesage/Exampleset, that would need a wizard-popup to specify the name/comment
