Improved some stylistic issues.
* Updated Travis CI reference to CircleCI.
* Switched to CircleCI "shield" style badge to fit in better with the other badges.
The debug output from Coveralls was rubbish. `"Build processing error"`
Besides some basics like checking if we were actually sending
valid JSON that gives us absolutely nothing to work with.
Technically 4.7 is probably fine for all but debugging symbols, for which a simple version check and workaround could be added. However, since all of the CI tests run 4.8 there is no regression prevention and it would be more future maintenance trouble than it's worth.
I've finally managed to build the release of KOreader for Android, but I've run into some issues.
I've updated the manual to reflect the solutions I've found.
The issues I've found are:
1. The version of the needed Android SDK platform isn't described anywhere;
2. xutils-dev is missing from the prerequisites, while it provides the `makedepend` utility used by the openssl build system;
3. Finally, for the Android build it is necessary to install JDK version 8.
Currently only tested on Ubuntu-touch emulator with framework
ubuntu-sdk-14.10 for armhf.
The ubuntu-touch port is binary compatible with the Kobo port
major changes in this PR are:
1. rename the emulator device to sdl device since both the emulator
and the ubuntu-touch target use libsdl to handle input/output.
2. ubuntu-touch app has no write access to the installation dir so
all write-outs should be in a seperate dir definded in `datastorage`.
