[PATCHv2] Script to add a new patch newpatch.sh

[Miguel A. Flores Silverio]

Script helps add a new patch to the soruce tree. It enables
the builid macro and uses the name of the patch as label instead of
using rpmdev-bumpspec.

*v1
 - Fixed: Fail adding a patch with no description
 - Fixed: Fail to add a patch outside the tree
 - Fixed: Fail when adding a patch already in the tree directory
 - Fixed: Fail to add to git when running script outside tree

Some tests I performed:
   # running script within tree and patch also withing tree, no description  
 - $ ./scripts/newpatch.sh some_patch.patch

# running script outside tree and patch outside tree, no description 
 - $ bash ~/kernel/scripts/newpatch.sh ~/Documents/fix_all_the_things.patch

# running within tree and patch outside tree, with decription
 - $ ./scripts/newpatch.sh ~/Documents/fix_all_the_things.patch "It is magic!"
