[Sugar-devel] From GConf to GSettings

[Emil Dudev]

Actually, when I started working on this, I changed the code in the
following way:
Read data from the GSettings database, write to both GSettings and GConf.
But I changed my mind, when I saw the article. Guess I'll make an
other commit, with my original idea.

As noted above, the only activities I have, which use GConf are read,
write and browse.
For read and write I have made the necessary changes to drop GConf and
I'll make the merge request in a minute.
For browse, I have made only a small change. But there is an other problem.

The problem with browse (and possibly, other activities) is that
GSettings does not allow new keys to be created at runtime. Moreover,
if sugar attempts to read a key, which doesn't exists, it will close.
An exception won't be thrown, it won't hang up, it will just close
with a single line in the log.
This is a serious downfall for activities, which use custom keys.
These keys have to be included in sugar's schema file, or sugar should
allow activities to define their own schemas.
