1.2.rev15

* in v1.2 the trash all buttons were bugged, fixed it
* if directory is hidden, it will not add it or any of its sub files or
sub directories into the xpi created
* got rid of downloadscommon.jsm, can open the downloaded file without
it (althogh thinking about it now, the jsm was better as now i copied
the function so its extra overhead, i should have left it, but whatever
now)
* put the zipping into a try-catch-finally so that zip is always closed.
there was a bug that once zip opened it would just hang
* deleted release folder, absolutely no need to keep that, its just a
copy
* hiding the options block as none of it is implemented and userbase
didnt exist to warrant it
* :learned: if you had any about:xpiler tabs open, you must reload them
for it to use the updated stuff
* on uninstall now deleting the history file
* made the load listener check regex case insensitive so it matches
about:XPILER too
* tried to make the div scroll to bottom of div after addMsg but its not
working, even if i try from scratchpad it wont work, so weird, i give up
on it for now
