/**
* Updates the specified module from the specified distribution.
* The order of operations is as follows: 1) Downloads _files list,
* _files.md5 checksum, _update script, and _update.md5 checksum,
* and compares them for validity. 2) Backs up the existing module
* to _backup/MODULENAME/VERSION/MODULENAME. 3) Parses _files list and
* creates any new directories, then downloads each file from the _files
* list and verifies it before saving it to disk. Files that have a
* special <skipIfUpdate>Yes</skipIfUpdate> tag are skipped.
* 4) Runs the _update script by eval()ing it. If at any time the
* installation fails, it sets an error message, calls restoreBackup(),
* and returns false immediately.
