Add geany-1.22

Geany is a small and lightweight Integrated Development Environment.
It was developed to provide a small and fast IDE, which has only a few dependencies from other packages.
Another goal was to be as independent as possible from a special Desktop Environment like KDE or GNOME.
Geany only requires the GTK2 runtime libraries.

Some basic features of Geany:
 - Syntax highlighting
 - Code folding
 - Symbol name auto-completion
 - Construct completion/snippets
 - Auto-closing of XML and HTML tags
 - Call tips
 - Many supported filetypes including C, Java, PHP, HTML, Python, Perl, Pascal (full list)
 - Symbol lists
 - Code navigation
 - Build system to compile and execute your code
 - Simple project management
 - Plugin interface
