v0.1 - Minimal Feature Release

easyCOM v0.1 is the first stable release with a working set of minimal features:

1. create customer record
2. add working time records with hourly rate
3. one-click invoice creation on unaccounted time records
4. export invoice as pdf (via Latex template)

The php backend stores in this first release in a local sqlite database.
