eMule 0.50a eMuleFuture 1.1

Citazione+       added better handling of removeable drives [WiZaRd] [idea by:  jedikalimero (http://forum.emule-project.net/index.php?showtopic=151569)]
* if you start eMuleFuture and your incoming and/or temp directories aren't found (e.g. if you use an external HDD and haven't switched it on),
  you are presented with a dialog with various options (cancel/try again/continue)
+       added kad term cleanup [WiZaRd]
* if you enter invalid chars in a kad search, you are asked whether you want eMF to strip the invalid chars
!       fixed addon dir writeability on some systems [WiZaRd]
!       fixed autoHL options [WiZaRd]
!       file buffer flush time was not saved [taz]
!       fixed fileinfo dialog corruption around bitrates [WiZaRd]
!       fixed missing icons in MiniMule [WiZaRd]
* this probably fixes all other strange issues with UPnP, source drops, etc.
!       fixed "ENTER" and "ESCAPE" keys in webbrowser [WiZaRd]
~       disabled sessionratio if we cannot upload [WiZaRd]
* this occurs mostly to "new" users... lowering their speed isn't such a good idea as they should become new sources ASAP
~       updated xSkinButtons to v1.50 [WiZaRd]
!       PS menu options are grayed out when partfiles are selected [taz]
