@/functions: Added functions autoloading support. Untested
Autoloading is done from separate files now. It is superior to
plain old vim autoload#functions only because it allows to hide
used functions from global scope and adds autoloaded plugins as
a dependency to plugin that requested a function.

         Creates a function out of given {funcdescr} (see

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
