Change install path of "programs" category

[NalaGinrut]

The default path of executable file is "~/.local/lib/guildhall/PACKAGE_NAME/bin". It's not convenient for users to specify the PATH env-var. My suggestion is to unify the executable path to "~/.local/bin". I can format a patch. What do you think?

According to the documentation, it is supposed to install it with a symlink in "~/.local/bin/", so this would be a non issue. However, a quick test package written by me isn't showing either behaviour.

okay, looks like files listed under the 'executable' and 'programs' categories are being installed with 'libraries'

OK, a link would be nice. Seems there should be a fix in Makefile
