Option to pre-configure output logging file

Currently Guake has an option to save the current terminal output by using the "Save to File..." right click option. When using this option to log the terminal output the data is limited by the configured scrollback lines number which is a limitation in a certain situations such as compiling or debugging where lots of output is produced (and unpractically long scrollback buffer would make scrollbar and scrolling back unusable).

There are many more use cases where an option to set logging in advance would be practical. Guake could simply continuously append output to a file and the log wouldn't be limited by buffering.
