A significant bug-fixing release (0.1.11) is pushed to extra-devel.

Bug fixes are:
1) There are various bugs in local portfolio. In particular:
- Improve delete button precision so less likely to accidentally delete portfolio/position.
- Fix a bug that make position in-deletable after creation.
- Fix a mouse focus issue that causes focus to leak to back button in position edit view.
- Add calculation of value/cost/gain/gain percentage for Yahoo positions. Please note that the "cost" you enter when creating a position is per-share cost. The app calculates the total cost for you.
2) Fix a layout issue in landscape mode when Yahoo position doesn't have daily price change.
3) Improve error message when there is no portfolio in google account.
4) Improve re-login procedure.

For the performance issue, I will try to isolate the impact on google and yahoo data processing to see which part takes more resource... the C rewrite of data processing is progressing slowly, I only got the login part done : p
