PHP Running Management 0.3 released

This release brings the project from a not very stable mono-user thing to a classy and functionality rich project, useable even by computer newbies who do not want to manage their data using SQL.

In particular this release included:
- More user-friendly pages for editing the data.
- New view (aggregated by month) was added.
- Many calculation and report presentation parameters became customizable.
- The design was improved a lot by using stylesheets.
