[Slogger] non ascii characters in Slogger logs

[cyberrus]

Hi all.

i'm really happy to have slogger back after little upgrade delay but...

1. i have problems with non ascii characters in XML logs - previous
version  converted all the text to UTF on-the-fly

2. i'd suggest having default description and keywords the empty string
- it means to clean them up between logging (now i have both the datas
from previous log and if i don't change them between logging all the
logs has same descrition and keywords)

3. where has the context menu option gone? it was very very usefull
