ref #6539 Fix build problems

• set Bundle-RequiredExecutionEnvironment back to Java 1.8
• Remove indigo osgi dependency from target platform

Merge branch 'LibrAlign' of https://dev.e-taxonomy.eu/git/taxeditor into LibrAlign

Conflicts:¶

eu.etaxonomy.taxeditor.molecular.lib/.classpath¶

eu.etaxonomy.taxeditor/rcp.target¶

Plugin molecular.lib refactored to use direct project dependencies. This should not be merged into trunk, since this is only for development state. (Currently the trunk is anyway already using different Maven dependencies.)
Adjustments to recent changes in JPhyloIO.

Fix repository location for target platform

Add PDE runtime environment to target platform (provides Plug-In Spy)

• updating versions due to release

MANIFEST.MF, feature.xml : removed dependency on specific versions
rcp.target : added vm arguments

corrected target definition

eu.etaxonomy.taxeditor/pom.xml : reverted addition of nebula widget jars
pom.xml : changed nebula repository to archived one
eu.etaxonomy.taxeditor/rcp.target : changed composite table jar widget to the one in the repository

added composite table dependency and classpath updates for 3.2.0-SNAPSHOT

switched to tycho 0.13 and added automated builds for mac and 64 bit windows

Updating target to include latest swtbot version and dependencies

Buckminster is dead, long live Tycho. The complete build can now be fully automated with eclipse tycho, Thus we will be able to have continous integration for the editor and automated builds by jenkins and all the glory. Removed all buckminster related files.
