PyLint cleanups in munkilib/installer.py.
Changes to munkiimport: 1) Always append version number to uploaded dmg or pkg if not there originally; code clean up around the renaming.
Fix dumb copy-and-paste error in last commit that caused munkiimport to crash with NameError: global name 'item_version' is not defined
logouthelper now properly checks both InstallInfo.plist and AppleUpdates.plist for 'force_install_after_date' items.
When skipping Apple Software updates because there is an update from Apple in InstallInfo.plist, remove AppleUpdates.plist to prevent MSU.app and logouthelper from presenting force_install_after_date warnings for items it will not be able to install because Munki updates are blocking Apple updates.
Better error checking when processing receipts and installs items when building our catalogDB; pylint cleanups
Patch from rmiddleton for updatecheck.isItemInstallInfo() -- fixes issue with multiple updates with the same name (but different versions) that need to be applied in a single session.
Store original Apple name for an update and use that when determining success of an Apple update install; new metadata functionality allows admins to override the display_name, which could have caused determining success of an Apple update install to fail, since it would have been looking for the wrong name.
Use consistent format when an item's version cannot be determined and is noted as '(newer than ...)'
Some Unicode/UTF-8 fixes for munkiimport.
If preinstall_script exits non-zero or installation fails, add item to skipped installs; for each install, if a prerequisite was skipped, don't install. Addresses issue 217.
Don't remove an item if another item that depends on it failed to be removed. This is the complimentary behavior to issue 217, which dealt with installs
