Delay on auto compilation useful

[GoogleCodeExporter]

In general the auto compilation feature of tikzedt is very useful. For more 
complicated figures that take more than a few seconds to compile (e.g. pgfplots 
which can take up to a minute for a high number of datapoints) it would be very 
helpful if the auto compilation would wait 1-2 seconds to see whether the input 
is finished. Otherwise a small typo, even if immediately corrected leads to a 
delay of the whole workflow until the compile finally aborts.
