preferences.txt crashes different versions of IDE

[powtac]

When different versions of the Arduino IDE are installed the preferences.txt file is the same for all installed versions.

This seems buggy, since the upload often works only when deleting preferences.txt while switching between different IDE versions.

A simple solution would be to add a version information to the preferences.txt file name. Like preferences-202.txt

Hello @powtac, can you provide the error message printed by IDE when the upload fails? or some other way to replicate the issue?

better solution is to use XML and made preferencies's tag backcompatible

Basically I had upload errors for month. I tried everything but nothing really worked. Then I realized that it works sometimes when I switched the Arduino IDE version. But not every time. I digged further and then found the solution. Not installing Adruino again helps, it was deleting the preferences.txt file from an other previous installed Arduino IDE.

For the detailed error I will check again...

Forgot to close this: preferences for arduino 1.5.x are now saved in Arduino15/.arduino15 folder

Thanks a lot for fixing this!
