#18 Libraries list "sticked" to shell prompt

[alexbruy]

I have found minor cosmetic issue. When printing libraries list, last line of the output get "sticked" to the shell prompt, like this

<library name="toolchains"/>
<library name="tta_tools"/>
</system>alex:~/devel/saga-gis-code$

This happens only with libraries list, modules list and individual tools does not have such issue. Proposed patch fixes this issue,
